I took an admittedly quick look at vf_drawtext.c and the helper routines. It 
looks like the only string quoting needed would be for '\' and '%', so not 
for a comma. I did not dive further into character processing. It does look 
like there's a substitution made for characters that can't be found in the 
font so it could be that the font is faulty or that the comma isn't really a 
comma (see prev. email).

Later,

z!
