[GRASS-user] v.label utf8 possible?

[Robert Kuszinger]

Glynn,

thanks for the answer.

"I wouldn't expect it to work with anything which
generates PostScript."

I also tested it not only with ps.map but also cairo ps output and ps
driver.
ps.map and ps driver fails with utf-8 vector using Biolinum font.
Ghostscript drops the an error on the resulting ps (see e-mail end)


Good news:

Cairo ps output generates even utf-8 d.vect correctly (with rasterized font
glyphs), but ignores

export GRASS_RENDER_PS_HEADER=FALSE
export GRASS_RENDER_PS_TRAILER=FALSE

settings. Well, this is understandable since these are PS driver options. A
beautiful combination would be to use the cairo PS output with the options
above... I know, it is something cairo internal...

thanks again
Robert
