LibreOffice HTML to PDF conversion, font config rule for lang fails












0















We are using LibreOffice 5.4 for converting HTML to PDF via UNO API. We have added some font configuration (fonts.conf) to select a particular Malayalam font when the language is Malayalam(ml-in)



<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match>
<test name="lang" compare="contains">
<string>ml</string>
</test>
<test name="family">
<string>sans-serif</string>
</test>
<edit name="family" mode="prepend">
<string>Meera</string>
</edit>
</match>
</fontconfig>


But when we convert a HTML containing Malayalam (ml-in) language using LO then this matching always fails but when we use wkhmtltopdf then this match is successful, so after debugging (FC_DEBUG) we found that the language comparison fails for LO i.e. the language is printed as hi instead of ml, why is it so? are we missing any configuration?
