Determine the LOGFONTA struct for the specified font. Note that
Pango internally uses LOGFONTW structs, so if converting the UTF-16
face name in the LOGFONTW struct to system codepage fails, the
returned LOGFONTA will have an emppty face name. To get the
LOGFONTW of a PangoFont, use <a href="pango-Win32-Fonts-and-Rendering.html#pango-win32-font-logfontw"><code class="function">pango_win32_font_logfontw()</code></a>. It
is recommended to do that always even if you don't expect
to come across fonts with odd names.</p>
