Agreed. But I was referring to the corresponding MathML (and the
combination of all three cases).
Best,

I can well imagine this being used in Statistics, or Statistical Mechanics, and related fields,
where the fraction is the ratio of integrals or summations or products
— especially for presentation slides, where the ratio of text width to line height is typically much less than in printed publications.
Of course you need to manipulate the TeX by declaring \displaystyle within the numerator and denominator, as David suggests. But not all that strange, afterall.

well if an author is coding directly in mathml probably wouldn't have
the mstyle.
If you're converting from TeX code (that is not using \mathchoice) then
you would need that for absolute fidelity, although to be honest often
if tex alignments end up being used in a subscript the author _doesn't
want the table to stay using large fonts, and ammends the code to use
mathchoice so it gets smaller.

I think the spec is clear, and the splitting of tex's \xxxstyle concept
into two separately settable parameters was certainly intentional:
3.1.6 says

That choice inevitably means that there are combinations not reachable
in TeX (and thus uncommon to most authors and probably unlikely
to be used except in exceptional circumstances) but I think it's clear
that the spec intends that they are reachable.

our changes to MathJax (following the results of this discussion); these
changes include resetting the scriptlevel to 0. To us, this seemed to make

To put it differently, we couldn't imagine how an author setting
displaystyle to "true" would expect to stay at scriptlevel=1 (for example).
The only use-case we could think of would be an array in a superscript or

However, as Fred pointed out, the spec seems to read differently. Since

<a shape="rect" accesskey="j" id="start6" name="start6"></a>I verified the latex set this morning and I think you are right that we
can not probably do better for the Unicode-to-LaTeX mapping. I attach
the updated LaTeX-commands.diff. Since I need the LaTeX-to-Unicode
mapping for my math converter, I now only take the "AMS" set as a
reference (+ some commands from itex2MML). The remaining issues for the
AMS set are the duplicate in

as well as the question mark for <AMS>\doublebarwedge ?</AMS> (should it
be \doublebarwedge or, to match unicode-math \vardoublebarwedge?).
Later, I'll try to analyze more carefully the difference between what I
get from unicode.xml and itex2MML (mathclass etc) and see if there is
anything relevant to say.

Do you know when the Unicode group will consider this change? (and
whether they have approved that?)

So it seems that this request to add set="latex-historical" has been
ignored. In my opinion, keeping these "latex-historical" entries is not
really useful since the changes are already recorded in the CVS history,
and actually I believe using revision control system is the proper way
to record this kind of info. The only potential problem I see is that
this CVS repository does not seem public... or is there at least a
public web page for that?

OK, actually I executed the wrong command for MathLaTeX-commands.diff.
Indeed, the three duplicates are still here but as you say that's
expected per classical tex limitation.
I now see new duplicates from the unicode-math set for
U03014 \lbrbrak
U03018 \Lbrbrak
U03015 \rbrbrak

seems to be fixed. The issue in the <AMS> set
(<a shape="rect" href="http://lists.w3.org/Archives/Public/www-math/2013Dec/att-0001/AMS-commands.diff">http://lists.w3.org/Archives/Public/www-math/2013Dec/att-0001/AMS-commands.diff</a>)
does not seem to be fixed though. "LEFT RIGHT DOUBLE ARROW WITH STROKE"
should probably map to \nLeftrightarrow (with an uppercase L) just like
it is done for the <latex> and <mathlatex> sets.

fixed at the time, updating from version 11 to 13 of the unicode data.

unicode still at revison 13, so this hasn't changed (unless I decide to
break from exact matching of mathclass data with the Unicode data)

That one is clearly wrong but it isn't necessarily wrong that you get
duplicate mappings in the latex to unicode direction. Classic Tex fonts
do not for example have a full Greek alphabet so both U+006F and
U+03BF ( latin o and Greek omicron) map to o. Al the entries in your
MathLaTeX-commands.diff file are of this form as far as I can see, Greek
letters with tonos being overloaded with latin letters with acute
which is not exactly a brilliant mapping but agrees with classical tex
usage.
By far the biggest set of incorrect mappings wer essentially all the
lowercase greek mathematical alphabet blocks having uppercase names.
I fixed those thanks.
Comments on some others in your LaTeX-commands-diff file below.
the first group is
U0002D -
-U02010 -
-U02212 -
that is ascii - and the explicit hyphen and minus characters all mapping
to - in latex, that again is the best you can do really if mapping to
classic 7bit fonts
-U0201A ,similar mapping the low quotation to a comma matches classical
TeX usage
-U02024 . One DOT leader, I suppose this could be \ldotp rather than .
(although that's the same character in the default setup)
-U02019 ' again using the ascii ' for the right quotation mark is normal
tex usage
-U00386 \'{A} as for the mathlatex usage this is the best approximation
you can do in classic tex font distribution
-U0212B \AA angstrom and A ring being same character, this seems correct
-U0219D \arrowwaveright
oops thanks, that's the left arrow....
-U025EF \bigcirc
size mapping to classical fonts is a bit strained, this is
"WHITE CIRCLE" and "LARGE CIRCLE" not sure I can do better but
suggestions welcome
-U022C5 \cdot "DOT OPERATOR" and "MIDDLE DOT" the latter is a bit of
abuse of the math font but again accords with 7bit cm font usage.
-U02662 \diamond diamond/lozenge
-U02729 \ding{73} two different white stars
-U02A63 \ElsevierGlyph{225A} This macro name is not actually usable to
anyone other than Sebastian I guess
-U00192 f f and script f.
-U00261 g same for g
-U1D716 \in
-U1D750 \in
-U1D78A \in
-U1D7C4 \in
Yes I guess I could wrap some of those in a math alphabet
(although classic tex mathalphabet commands do not affect the standard
definition of \in)
-U0039C M
Mu=M.
-U1D6B3 M
-U1D6CD M
-U1D6ED M
-U1D707 M
-U1D727 M
-U1D741 M
-U1D761 M
-U1D77B M
-U1D79B M
-U1D7B5 M
Mu=M but I added the math alphabets \mathbf{M} etc
U02306 \perspcorrespond
-U02A5E \perspcorrespond
Not sure either of these are really defined in classic tex setups,
I made one var... (to match unicode-math)

ah I'll see what I can do....
Although it really isn't so clear in a unicode setting that saying
U+03B1 is traditionally mapped as \alpha really helps.
U+03B1 is (as you know) textual Greek, and mapping it to \alpha
with the traditional definition of \alpha will just lead to tex errors.
Perhaps I can document that if the character element has mode="math"
then the <latex> mapping is only assumed to work in math mode.
But in anycase the errors you reported initially were just errors
I think not relying on such details, I'll try to get that done.....

Is there any update on this or a plan to lead to reliable set of LaTeX
mappings (in the last version of unicode.xml I still see some of the
errors I initially reported and no set="historical") ? As I see, the
unicode-math names are not really "standard" (whatever it means for
LaTeX), for example "GREEK SMALL LETTER ALPHA" is mapped by "\upalpha"
instead of the more traditional "\alpha". Just marking the legacy
mappings "historical" without fixing the errors, will not be very
helpful for someone willing to rely on this set.
