Hi,
I do not understand why the function hb_shape returns glyphs instead of
unicode characters. I understand that different fonts could have
different glyph indices for a given symbol, but Unicode does not depend
on the fonts, so it would be more usefull to return Unicode indices.
For instance, I used fribidi in the past and it returned the visual
string in Unicode format. I think that hb_shape does pretty the same
thing. The only reason I imagine is that not all the glyphs may have an
index in the Unicode table, so it would be imposible to represent them
all as Unicode indices, but I don't know whether it is true.
Is there a way to convert the given glyphs into Unicode indices?
Is there any literature about layout processing for not having to ask
these kind of questions in the list? I'm very lost on what to expect
from i18n libraries.
Thanks a lot.
