gucharmap is a GTK2 program and these are always searching for
fallback fonts for every single glyph which cannot be displayed yet
with the fonts already loaded. This is a very nice and useful feature
because one almost never sees missing characters.

But of course this makes gucharmap useless for checking whether a
certain font has an Euro or not. If you grep for fonts in
/proc/{pid}/maps for the pid of gucharmap, you will see that
gucharmap loaded several fonts and not only "Bitstream Charter".

For checking whether a font has a certain glyph I currently often use
"xfd -fa" but then one also has to make sure that the correct font has
really been opened (for example with FC_DEBUG).

Another good way for checking is using a font editor like "fontforge".
