Cluster matching 1b

Description:

5.3. Cluster matching
http://www.w3.org/TR/2013/WD-css-fonts-3-20130711/#cluster-matching


In the numbered list, what should follow if 1b holds true?

"If a sequence of multiple codepoints is canonically equivalent to a single character and the font supports that character, select this font for the sequence."

Is this implying (though not stating, note), that the text should be normalized so that the glyph for the canonically equivalent character can be used? (I'm not sure that's a good idea.)

Or is the meaning that if the font has a glyph for the precomposed character that is canonically equivalent to the sequence of characters, then that glyph should be used (without changing the sequence of characters itself). That would seem to make more sense.

Otherwise, it's not clear why you would select the font for this sequence.
