I was able to reproduce with latest ttx and the ttf file that @laerm0 linked to above. I’ll investigate, thanks.

yeah, for some reason an inline comment in the VTT code contained in one of the TSI tables (TSI3, i think) contains an invalid control character U+000B. This is invalid in XML, so the expat parser chokes. There is an open issue on fonttools about dealing with invalid XML chars: https://github.com/fonttools/fonttools/issues/71

for the time being I would recommend editing the VTT sources and deleting the offending character, which is located at line line 422637, column 66 in my ttx dump (check the expat error message).
