[Talk-in] Indic rendering

[Mikel Maron]

Vardhan

Different issue from CJK characters.

"I believe the underlying issue here is that Mapnik is rendering the string one character at a time in order to make the characters follow along the path. These Indic languages use ligatures where the rendering depends on multi-character sequences and can not be correctly rendered one character at a time,"
