#1330: wxGUI: "UnicodeEncodeError: 'ascii' codec can't encode characters" in
pl_PL.UTF-8
----------------------+-----------------------------------------------------
Reporter: msieczka | Owner: grass-dev@…
Type: defect | Status: new
Priority: major | Milestone: 6.4.1
Component: wxGUI | Version: svn-releasebranch64
Keywords: | Platform: Linux
Cpu: All |
----------------------+-----------------------------------------------------
Debian squeeze amd64, releasebranch_6_4 r45717.
1. Start wxGUI in pl_PL.UTF-8.
2. Add any raster or vector layer.
3. Change it's opacity level.
Try to save a project - error:
{{{

Can't also remove the problematic layer from the list - similar error:

> Name of raster/vector contains only ASCII characters?
Yes. The culprit seems to be the Polish word for "opacity" -
"nieprzeźroczystość", which wxGUI has problem to deal with.
I do not have any accented characters in file/directory names, use UTF8
czech encoding and I do get this error when trying to save the workspace
.grc file (GRASS 7.0). Apart of alphanumeric characters, my maps contain
only '-' and '_' characters.
The problem to save workspace file is the same in GRASS 6.4.1,
LANG=cs_CZ.utf8.
When grass64 or grass70 started with LANG=C, no errors. WAIT: after that,
trying it again with my normal LANG=cs_CZ.utf8 setting (starting with just
grass64 or grass70 commad), no error anymore! Seems like by temporary using
LANG=C, something "initilalized" properly, and the problem is gone. I will
try to reproduce that on my other machine and also look, if the "fix"
persists after reboot (tomorow).
Below is copy of text of error message window popping up after the first
attempt to save the workspace in 6.4.1. In GRASS 7.0 similar error message
appeared in the terminal. I also observed similar error in 7.0 when trying
to add an action in WxGui modeller (but not in 6.4.1).
Might be also of interest:
I'm running 64bit Debian wheezy based Linux Mint.
GRASS 6.4.1 comes from debian binary package.
GRASS 7.0 was compiled from svn few days ago (ver. 7.0.svn46654).

OK, so I did a few tests on my notebook, all in GRASS 6.4.1. Every session
has these steps:
* start GRASS with a locale (LANG=something /usr/bin/grass)
* open a mapset (same in all tests)
* load a raster or two into map view
* try to save the .grc file
Instead of the LANG=C I used LANG=en_US.utf8, which also works (more on that
later).
The tests:
1) GRASS with my default cs_CZ.utf8 locale: Saving .grc file *fails*.
2) GRASS with en_US.utf8 locale: Saving .grc OK.
3) GRASS with my default cs_CZ.utf8 locale: Saving .grc file OK.
4) Reboot
5) GRASS with my default cs_CZ.utf8 locale: Saving .grc file OK.
So it really seems that temporarly using English cures the problem.
In the meantime I also observed (but it was in GRASS 7) that with LANG=C
there are problems with '@'character in names of layers (layer@mapset).
That's why I use rather en_US.utf8 in these tests

are you also changing opacity level at this point?
are you also changing opacity level at this point?
or renaming the map layer (using non-ascii characters).
I did not change the opacity AFAIK, but yes, there somehow appeared the
(průhlednost 100%) note in the list of layers and that was the cause (in
english there is (opacity 100%)).
BTW the word "průhlednost" is wrong translation, there shoud be
"neprůhlednost".
