I'm learning the fontconfig API, and I'm trying to figure out how to do the
I have arbitrary Unicode text, and I would like to match a reasonable font
to use for displaying it. It's possible that I might need more than one font
if, say, the text is a mixture of Latin characters and Asian ideographs.
I see that FC_CHARSET is an option to FcPattern. Does this sound like I'm on
the right track:
A) Construct an FcCharset and add all unicode characters in the text to
B) Add it as a FC_CHARSET value to an FcPattern.
C) Use FcFontList() to search for the matching font.
The developer reference contains the following statement: "Fontconfig uses
some of these properties for font matching and font completion. Others are
provided as a convenience for the application's rendering mechanism."
So, I guess I'm trying to clarify whether I can use the FC_CHARSET property
to search for fonts that have coverage for my unicode text, or if this a non-
searchable property, only.
