The problem with old style number in math is that it might cause
something like, say, old style 4 or 9 to be mistaken with a subscript
one.

Well, I trust you. But from my experiments, all the OpenType families
that have both text and math fonts only have old style number in the
text fonts. If these are new families start providing old style numbers
for the math font too, then it will be easy to update the CSS rules in
my MathFonts repository to take them into account.

Khaled Hosny pointed out that old style numbers are available for the
text font and don't really make sense for the math font. So I updated my
GitHub page to reflect that. Now, as I see, all the free fonts have old
style numbers, but only Asana Math and XITS Math have calligraphic scripts.

## UNDJuly 25, 2014 Old-style numbers and calligraphic letters in OpenType math fonts

Author: | Channel: www-math@w3.org Mail Archives

Dear all,

I've updated my repository of OpenType math WOFF fonts to add some CSS
rules for old-style numbers and calligraphic letters:

http://fred-wang.github.io/MathFonts/

So the current status from my testing is

- Asana Math and XITS have calligraphic variants.
- Asana Math, Neo Euler and XITS have old style numbers.
- Other fonts do not seem to have such variants (or they are proprietary
and I can test them).

I listed all the possible syntaxes, either with
font-variant-numeric/font-variant-alternates not yet enabled/implemented
in browsers or font-feature-settings with/without browser-specific prefix.

I supposed you understood that it is not "just because new things will
be supported" ;-)

First the Unicode-only constructions in arbitrary fonts will still be
supported, what we want to remove is the old font tables for Asana Math,
"STIX General" and MathJax. Asana Math and the "STIX Word" set have an
OpenType MATH table so can be used with the new code. Additionally,
Latin Modern Math is a "modernized implementation of the Computer Modern
fonts" (with reshaping and other stuff that are out of my area of
expertise, see the papers on the GUST website for details) and so can
now replace the "MathJax TeX" fonts (which is just generated via an
autotracer, targeted to MathJax's needs and was a temporary solution to
replace the old BaKoMa TeX support). So first, nobody should need these
old fonts in the long term since you have equivalent OpenType MATH
version... why do you want that??

The technical reason why we want to remove support for these old fonts
is that they need special handlings which make the stretchy operator
code "complicated" (to use an euphemism). Since we want to optimize it
in the future, we will need to cleanup the code before refactoring it.
Moving to OpenType MATH has actually been the plan for 7 years, but that
finally could only be realized recently, thanks to the Ulule crowdfunding...

Moreover, from the user's point of view, you will get a much more
consistent way to use the various OpenType MATH fonts in WebKit/Gecko.
Basically, you now have only one single Math font to deal with and only
need to set the font-family on the [itex] (and perhaps the companion
fonts for the text). All the mathvariant selection, correction of prime
size, math layout parameters, stretchy op constructions etc are stored
in the font and Gecko&WebKit only need to read what has been specified
by the font authors. One can even create his own math fonts with
fontforge and they will be immediately supported by Gecko&WebKit without
having to hardcode new data. For example, if some Mathematica people
read that, they could just make an OpenType MATH version of their fonts
and restore the original 15-years old support in Gecko :-)

## UNDJuly 21, 2014 RE: Tie over infinity

Author: | Channel: www-math@w3.org Mail Archives

The only time I have seen them in Context is in some mid 1800’s treatises for the incomplete infinity and in a few documents concerning uncountable infinity from the early 1900’s, I have not seen their usage in any mathematical texts after the 1950’s that I can recall. It would seem their usage fell out of favor. Instead Aleph and Beth Cardinal Numbers, א U+05D0 ב U+05D1 replaced Uncountable Infinities, and (INCOMPLETE INFINITY) U+29DC ⧜ or (PROPORTIONAL TO) U+221D ∝ or (INFINITY NEGATED WITH VERTICAL BAR) U+29DE for incomplete infinity.

## UNDJuly 20, 2014 Important information about the MathML fonts in Gecko 31

Author: | Channel: www-math@w3.org Mail Archives

(apologies for possible multiple copies ; feel free to forward this message)

Dear all,

Starting with Gecko 31 (to be released the week of July 22), the
recommended fonts for the MathML rendering are mathematical fonts with
an OpenType MATH table [1]. The old math fonts (e.g. MathJax TeX, STIX
General) are now deprecated in favor of the modern OpenType math fonts
(e.g. Latin Modern Math, XITS Math, Cambria Math). There are still some
known bugs/limitations in Gecko, math fonts and systems so that might
take some time before the migration can be fully done. However, note
that we plan to remove support for the old fonts in a near future, so
find. In particular:

* For Web users: If you installed MathML fonts in the past, please
documentation of the recommended math fonts. On desktop, if you use
Windows >= 7 or if you have a TeX distribution installed, it's now
really likely that you don't need to install additional math fonts. On
mobile devices, the MathML fonts add-on [3] is still the only option for
now but we have work-in-progress patches for Android and FirefoxOS.
Currently, there is not any native feature to configure your preferred
math fonts, but Firefox users can try the MathML-font-settings add-on [4].

* For Web authors: If you use Web font versions of deprecated math fonts
(e.g. MathJax TeX or STIX General), perhaps with the help of the
::-moz-math-stretchy pseudo-element, you should update your pages. The
rule is now very simple: just apply the desired font-family on the
[itex] elements. You might also provide WOFF fallback or additional
font-family for the text. Download [5] to get WOFF fonts together with
CSS stylesheets to use on your Website.

* For software maintainers: Please ensure that an OpenType MATH font is
available on your system or that the appropriate dependencies for
Gecko-based programs are set. You might also want to remove obsolete
fonts or at least drop the dependencies for Gecko-based programs.

* For font designers: You are invited to create your own math fonts and
test them with Gecko. Note that fontforge has menus and a Python
interface to do that [6] [7]. Existing math fonts have issues with
ascent/descent, please be sure that the OS/2 metrics are consistent, so
that they work the same in all platforms/browsers.

Related news:

* The STIX fonts (STIX-Word set) have an OpenType MATH table, but there
are known to have many bugs. The STIX Consortium announced version 2.0.0
for early 2015 but for now, it is recommended to use the XITS fork

* Partial support for the OpenType MATH table is also available in
WebKit Nightly and will improve the rendering of MathML operators [9].
Requests to make OpenType MATH font installed by default on iOS & Mac
systems have been submitted to Apple.

release notes below. As usual, you can check
https://wiki.mozilla.org/MathML:Home_Page#Last_bugs_fixed and
https://developer.mozilla.org/en-US/Firefox/Releases/31#MathML for details.

* Gecko 31:
- Remove obsolete/non-standard features: font.mathfont-family*
preferences, ::-moz-math-stretchy pseudo-element, STIX 1.0 beta support.
- The scale correction is no longer always applied to stretchy
operators, to follow the TeX / Open Type MATH behavior.
- Fix some bugs with dotless i's and j's, one-argument mrow and
invisible operators.
- lspace/rspace now only have effect on embellished operators inside
(inferred) mrow.
- Fix a bug with the columnspacing of rtl mtable.
- Use Unicode Mathematical alphanumeric characters for
bold/italic/bold-italic mathvariants
- Initial implementation of the MathVariants Table of the Open Type
MATH table. See
https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/Fonts

* Gecko 32:
- Implement menclose notation "phasorangle"
- Other improvements to the MathML stretchy code.

* Gecko 33:
- Add support for mtable@rowspacing/columnspacing/framespacing attributes
- Use Open Type MATH constants for fractions, stacks, radicals and
scripts

As far as I understand, you have no other way than really going native in this process since MathType equations are embedded objects.
I would give a last chance from the flash side of the world, which has a tendency to be a tick less protective or to a trusted Java applet which does have full access to the clipboard (we were able to implement the MathML clipboard operations for example within the Wiris OpenMath Input Editor using that, for example).

I would assume that the fine team at Design Science, two of them are on this list at least, would be able to dig out solutions, since they are the makers of MathType. I would expect solutions to be dependent on just about any combination of versions (OS, Word, MathType).

Originally, we were a TEX-based publisher, but we have been steeped in XML/MathML for about a decade. We are trying to implement a process whereby authors who have developed content in Microsoft Word with a MathType plug-in can cut and paste that content into a web form running on a Linux server.  The goal is to retain all/most of the XML/MathML coding of equations, or to have post-processing where we end up with that coding after the submission. That's the bottom line.

I appreciate the input.

But I'm not really interested in rendering MathML per se, be it with the help of CSS or any other "hack".

In the context of handwriting recognition, what I want is to get a sense of which MathML markup I should produce that could be consumed by any renderer and achieves alignment similar to what's been written.

I attached yet another screenshot in which you can see a handwritten long division in the center, on the left is a LaTeX render achieved using array and on the right is the MathML markup I'm generating so far. As you can see, the fact that the decimal dot takes a column makes me insert <none/> elements to keep things aligned.
