"<p>TQt has a powerful font substitution feature that allows you to "
"specify a list of substitute fonts.  Substitute fonts are used "
"when a font cannot be loaded, or if the specified font doesn't have "
"a particular character."
"<p>For example, if you select the font Lucida, which doesn't have Korean "
"characters, but need to show some Korean text using the Mincho font family "
"you can do so by adding Mincho to the list. Once Mincho is added, any "
"Korean characters that are not found in the Lucida font will be taken "
"from the Mincho font.  Because the font substitutions are "
"lists, you can also select multiple families, such as Song Ti (for "
