Input fails to render with a lexing error

The given example fails to render in PNG mode with a lexing error (can someone put this in plaintext in the bug report, so it's easier to reproduce?)

Extracted out of bug 48032.  Screenshot by praveenp.
Comment 1 This, that and the other (TTO) 2014-11-12 04:09:01 UTC
This is enough to see the bug:

<math>ക</math>
Comment 2 This, that and the other (TTO) 2014-11-12 04:11:04 UTC
The example in comment 1 gives the error "Failed to parse (lexing error): ക"

This example:

<math>\text{ക}</math> 

gives a different message: "Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): {\text{ക}}"
Comment 3 praveenp 2014-11-15 04:11:09 UTC
This bug is not limited to Malayalam only.

Examples: Tamil: <math>\text{ப}</math>, Hindi: <math>\text{ग}</math>
Comment 4 Matthew Flaschen 2014-11-15 05:01:19 UTC
This particular bug report is limited to Malayalam.  Those are not just different languages, but also different alphabets, meaning a fix for this bug (e.g. a new font) will not necessarily fix those.

So if you want to track those other alphabets, please file separate reports.
Comment 5 C. Scott Ananian 2014-11-15 05:13:08 UTC
I don't think it's a font issue, I think it's a TeX validation issue.

Does this bug occur with Mathoid enabled?
