Hi David,

Malayalam in FreeFont has been broken for some time.

There was a big push to support reformed script a few years ago, but it was a train wreck. First, there was at the time a bug in Harfbuzz, whereby it activated 'MLR ' by default. I don't know if this has been fixed, but at the time, in an attempt to gather support to get that fixed, we ran across Malayalam speakers who were vigorously opposed to anything suggesting a whisper of a connection to the reformed script, and who insisted that we remove it forthwith. (Along with other demands.)

(I can say, I have read elsewhere that not everybody has such strong feelings one way or the other about which script is used, and thing both have their place.)

This is one of the big decisions I have to make before releasing the font.

Thanks for your report!

In FreeSerif, "'kern' kerning in Malayalam" does not apply to language system 'MLR ', so kerning is not applied to mal_ra.pstf in Malayalam’s reformed orthography. For example, this is kerned:

data:text/html;charset=utf-8,<div style="font: 300px FreeSerif; font-language-override: 'MAL'">%E0%B4%A0%E0%B5%8D%E0%B4%B0%E0%B4%9E%E0%B5%8D%E0%B4%9E</div>

but this, where the ra is in a different position but which should look the same as the above, is not kerned:

data:text/html;charset=utf-8,<div style="font: 300px FreeSerif; font-language-override: 'MLR'">%E0%B4%A0%E0%B4%9E%E0%B5%8D%E0%B4%9E%E0%B5%8D%E0%B4%B0</div>
