How to determine which LOGFONT charset to use?

Question

I have a text selection / specification dialog, where the user can specify the font from a list, set bold, italic, etc. I then use the info in a LOGFONT to create a CFont to subsequently use in a CEdit as a preview.

However, if the user picks a symbol font like Wingdings, the preview doesn't work correctly unless I set LOGFONT::lfCharset to SYMBOL_CHARSET. So, essentially given only a font name, how do I determine what the default charset should be (ie, how can I tell if I should us SYMBOL_CHARSET)?.

I've seen suggestions to use GetTextMetrics(), but that involves setting a font into a DC, and I haven't created the font yet, so...?

Answer 1

Once you have the name of the font, you can use EnumFontFamiliesEx to see if that font exists for a particular charset. You can call it once with DEFAULT_CHARSET and, if that doesn't work, call it again with SYMBOL_CHARSET.

That's a guess anyway. I haven't had a chance to try it myself.
