z-buffer and pattern, modified vowels

[Harald von der Osten-Woldenburg <hvdosten(at)lb.netic.de>]

Hi out there,

two small questions:

(1) the german language uses modified vowels (some strange letters...).
Is there really no chance to come along with them in the IDL's
font-libraries? I mean "ae", "ue" etc

(2) z-buffer: and also no chance working with patterns in the z-buffer?

patt = bytarr(12,5) & pat(0,0) = ... & polyfill,..., pat=patt

for example works fine, but not in the PS- and Z-surroundings. Is there
any trick to be able to work with this?

Thanks again for every small hint

Harald
