One solution to the bug (6.85 KB, patch)

Description mark_sweep 2004-12-23 21:22:25 UTC
The upper case Greek characters that are undefined in plain TeX (such as \Alpha,
\Beta, \Epsilon, etc.) are rendered in TeX's math italic font.  They should be
rendered in an upright ("roman") font to match the other Greek characters
(\Gamma, \Delta, etc., which are defined in plain TeX).

This affects the function "find" in math/  I don't understand the
code well enough to tell whether replacing FONT_RTI with FONT_RM would be
Comment 1 Tomasz Wegrzanowski 2005-05-07 00:48:23 UTC
Replacing FONT_RTI with FONT_RM would be sufficient.
Only FONT_* influence the italicness.

One solution to the bug

It's not enough to set it as FONT_RM, it will still be displayed as italics. So
instead we change it to use FONT_UF and specify the letter as a \mathrm{},
forcing ams even perhaps it's unnecissary (the main mathrm definition force
ams, so to keep is likewise)

Fixed in r17386.
Comment 4 Nicholas Longo 2011-10-14 02:08:04 UTC
This bug is fixed in texvc, but on the various WMF wikis there incorrect images are cached and cached math images never expire.  (See bug #24445).
