Re: Using the Symbol font with pango

[Timothée Lecomte <timothee lecomte ens fr>]

Dear Pango enthusiasts,

Just to inform possible list readers, I have managed to handle the 
Symbol font by manually translating characters to their official unicode 
counterparts, as defined in the Unicode offical website : 
http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/SYMBOL.TXT

I simply iterate on each character of my input string, translate the 
character via glib utf-8 functions.

It may not be optimal, but it is satisfying for me.

Best regards,

Timothée Lecomte
