Yup. But only in the non-UTF version...

I don't know. But if I start xterm with the strange font there's no
error from X11.

Ah well, I didn't realize that I *have* to use UTF-8 if support for it
is enabled in ion. Is that what you're saying? If so then I really would
suggest taking out the UTF support as you can't expect from anyone
installing ion that he switches to using UTF-8 fonts and all...
(After writing this mail I don't think it works this way).
But anyway I tried your font and ironically I get an error message:
----snip----
>> Could not load font
>> "-misc-fixed-bold-r-normal--18-120-100-100-c-90-iso10646-1", trying
"fixed"
>> Failed loading fallback font.

[Skipping unnamed C functions.]

Now, I *have* checked that the font exists and it works in an xterm too.
I get the same error message when starting ion by "LC_ALL=de_DE
ion-devel" only this time ion succeeds in loading the fallback font.
Using "-misc-fixed-bold-r-normal--18-120-100-100-c-90-*-*" succeeds for
"LC_ALL=de_DE" and results in invisible fonts for "[EMAIL PROTECTED]"
but this time without the error message...
Looking at the code it's this function that fails:
XCreateFontSet(wglobal.dpy, fontname, &dummy_missing,
&dummy_missing_n, &dummy_def);
The manpage says:
----snip----
If XCreateFontSet is unable to create the font set, either because
there is insufficient memory or because the current locale is not sup-
ported, XCreateFontSet returns NULL, missing_charset_list_return is
set to NULL, and missing_charset_count_return is set to zero.
[...]
If no font exists for any of the required charsets or if the locale
definition in Xlib requires that a font exist for a particular charset
and a font is not found for that charset, XCreateFontSet returns NULL.
Otherwise, XCreateFontSet returns a valid XFontSet to font_set.
----snip----
So it seems that LC_ALL set to de_DE or [EMAIL PROTECTED] requires ISO8559-1
and ISO8859-15 fonts respectively. (And we also see X enforcing that,
what an irony :))
Ah well, I'll go playing a bit with the code - hopefully learning a bit
about X11 and fonts along the way... :)
I'll be back when I know a bit more...
Cheers,
Mika
