Re: [gtk-i18n-list] Rendering a custom glyph using pango

[Ferdinand Ramirez <ramirez ferdinand yahoo com>]

I am using ubuntu linux and tried to insert the string into a GtkTextBuffer using gtk_text_buffer_insert after calling g_locale_to_utf8 on the value. Maybe, my syntax is wrong.

For a value such as 46DB, I first call g_strdup_printf("%s", "\u46DB") and the gchar * that is returned is what I pass into g_locale_to_utf8.

For a value like 10005, it looks like I cannot use the above method like \u46DB.

Apart from making it work, I am also curious to know which part of the code actually loads the font file and extracts the glyph and how the code flow occurs from gtk through pango. 

Thanks a lot,
-Ferdinand
