I'm a little fuzzy about exactly what that means, too.
But that seems to be right. I can paste any character
from the Character Map application into a word and have
it rendered properly as long as it's unicode value is
less than or equal to a decimal value of 255. Higher
than that, I appear to be out of luck.
Cheers,
David

So David's cut'n paste from the Character Map works only because the
chosen character was in the first 256 characters - but the !Z notation
does not work because IDL wasn't coded to interpret that notation in
that case (widgets). Is that what that means?

Actually, a TechTip may explain it better than I could:

Well, it would save me from having to locate that
damn character map application on my computer all
the time! :-)

Yes, but why not? Clearly the thing I am asking for can
be *done* in hardware fonts, since I've managed to do it
another way.

According to the online help embedded formatting commands do not work
with hardware fonts. Checking if the device is able to utilize those
commands involves seeing if bit 12 of the Flags field of !D System
Variable is set.
i.e.:
IF (!D.FLAGS AND 4096) NE 0 THEN PRINT, 'Bit is set.'

Ok, I'll bite - is there some reason to expect "!Z(225)" to look like
anything other than "!Z(255)"?

Well, "properly". It illustrates the problem on my

Out of curiosity, do the characters also display correctly on X when
grabbed from the Windows character map?
Thanks,

Karl can probably speak more authoritatively on this topic,
but I think this is a can of worms. :-)

I find it impossible to construct a string using unicode
characters for display in a widget. However, if I use the
unicode characters (an accented a, for example) in a string
(I probably used the Windows Character Map application to
grab the right character), then this is *usually* displayed
properly.
Cheers,
David
