[MapServer-users] Multi language worldmap (basemaps)

[Richard Duivenvoorde]

Ok, more or less found a partial solution.

(but anybody with experience in a multilingual world map and labels, please let me know)

Using some python from
https://unix.stackexchange.com/questions/247108/how-to-find-out-which-unicode-codepoints-are-defined-in-a-ttf-file
I'm now able to find in which ttf font a missing glyph can be found...

Using the following in my fonts.lst:

sc fonts/DejaVuSansCondensed.ttf
scb fonts/DejaVuSansCondensed-Bold.ttf
noto fonts/NotoSans-Condensed.ttf
notob fonts/NotoSans-CondensedBold.ttf
uni fonts/unifont_sample.ttf
unib fonts/unifont_sample.ttf
tw fonts/UKIJCJK.ttf

And using
FONT "sc,noto,uni,tw"   # does order matter?

I have a start to show labels in my small test setup with combined data from Pakistan, Taiwan and Afghanistan...

I still have other log messages now:

AH01215: Unable to load glyph 62314 for font "uni". Using ? as fallback.: /usr/lib/cgi-bin/mapserv
[Fri Apr 14 10:12:20.644638 2023] [cgi:error] [pid 141599] [client ::1:46140] AH01215: msGetGlyphByIndex(): General error message. unable to load glyph 62314 for font "uni": /usr/lib/cgi-bin/mapserv

while my script tells me 'glyph 62314' is in 'fonts/unifont_sample.ttf'...

Any info or insights are still being appreciated :-)

Regards,

Richard Duivenvoorde
