Hi,
Using * in superscripts gives wrong glyph size and spacing.
For example, with LM math everyhing looks fine:
\starttext
$x^*$ vs $x^{\ast}$
\stoptext
With Cambria, the result is OK (but you can still see the differences in
the spacing of * in x^*)
\usemodule[simplefonts]
\setmathfont[Cambria]
\starttext
$x^*$ vs $x^{\ast}$
\stoptext
With Neo Euler, $x^*$ look really bad.
\usemodule[simplefonts]
\setmathfont[Cambria]
\starttext
$x^*$ vs $x^{\ast}$
\stoptext
I cannot figure out why this is happening. It definitely looks like a bug
at the context end rather than a bug with the fonts.
Aditya

Indeed. Making this change gives the correct result. @Hans, can you make the following change in char-def.lua --- char-def.old 2012-02-22 17:18:05.000000000 -0500 +++ char-def.lua 2012-02-22 17:19:06.000000000 -0500 @@ -382,8 +382,7 @@ description="ASTERISK", direction="on", linebreak="al", - mathclass="binary", - mathname="ast", + mathsymbol=0x2217, unicodeslot=0x002A, }, { Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 7+ messages in thread
