Created attachment 189058 [details] Math screenshot showing Circumference formula example on Thai locale Example formulas in Math refer to symbols with unlocalized names, such as "%pi", while localized names are required when inserting symbols manually on locales such as Thai. This makes the example formulas rendered with raw symbol names, rather than the actual symbols.
FYI, I have untranslated all symbol names for Thai in master. It's also more appropriate for Thai users to use original English names in codes, as there are several localized versions in use in text books, although there is a standardization effort by the Royal Academy. With the untranslated names, the problem is gone. But the inconsistency of symbol names in examples is still a valid bug. They should still be localized anyway.
Resolving this as duplicate of bug 32415, instead of localizing the examples, it is now possible to use English symbol names regardless of the locale. *** This bug has been marked as a duplicate of bug 32415 ***
