Hi Alex,
current @lib/ps.l does not deal with utf well enough and comes with a
workaround involving bin/lat1.
Bellow is a prototype code for displaying utf characters in poscript
insired by

Hi Alex,
there was a bug in the previous code:
> ((<= 130 C) # utf
>(let? L (cdr (assoc C *PsGlyph))

> (prin "[")
should be:
((<= 130 C) # utf
(let? L (cdr (assoc C *PsGlyph))
Hi Tomas,
I would presume that you are beginning to get close to the reason that
one often encapsulates strings into an object. You need to know the
display length of something to center it, and that means that you want
to know the length of the string. Without an encapsulating object, you
need to
Hi Tomas,
wow!! That's what I've been looking for since a long time!
I never found a way to use other characters than ISO-8859-1 in
"lib/ps.l". I even asked once in "comp.lang.postscript" witout avail.
I'll try it now, and build it into "lib/ps.l" when it works.

While this is often useful, I think it will not help here in this
Hi Tomas,
now I experimented a little with the glyphs. I would suggest that we use
an 'idx' instead of an 'assoc' list, as there might be quite a lot of
entries.
So I put "glyphlist.txt" in "lib/", and this code in the beginning of
"lib/ps.l":
# *PsGlyph
(in "lib/glyphlist.txt"

This is a serious problem. I cannot see a way to send the string to the
PostScript interpreter for the 'stringwidth' calculation. Does anybody
have an idea?
Cheers,

yes, seems like a good time for me to learn the new function:-)

Hmm, it should be there:

Aaah, sorry! I made an error when editing the tar script :-(
Now it should be correct.
