Please provide the ad click URL, if possible:
I noticed that underscores and backslashes in plmtex text appear as
centered dots with the xwin driver, but as underscores and
backslashes with the xcairo driver. I also notice that these two
characters appear as centered dots with both drivers in example 6,
which uses plploin...
The caret/circumflex character appears as a degree symbol, which is
also problematic (IMHO), but at least it's consistent with PGPLOT...
I looked into where/how to rectify this, but I don't (yet) understand
PLplot's text encoding and font handling well enough to make progress
myself. Can anybody help me out here?
