Any attempts to run some GUI parts result in a partial or complete failure
with CLI filling with UnicodeDecodeError messages. r74306 is fine, r74307
breaks everything.

I think we do not want to revert r74307 but rather bisect the problem with
wxPython 3. Maybe in a docker environment?

On RHEL7, there is no wxPython4 available AFAICT, and RHEL7 will be an
important production system until about 2024.

IMHO, GRASS 7.x must run on RHEL7 and other currently supported production
systems. We can break this with GRASS 8.

There is no v4 in Gentoo and also Ubuntu LTS (only one year old) sits on
v3. Due to required changes in various other packages using wxPython, v4
widespread adoption will take some time.

Yes, we need to support both Python 2 and 3, and wxPython 3 and 4, at
least for some time.

Regarding this ticket, I believe it's Python 2 vs 3 problem, not wx 3 vs
4.

I could not reproduce this either on Python2 or Python3. That's why I
suggested that it might be related to WX. I tried again on current trunk
and I still can't reproduce it. I will try to install wx3 on my virtualenv
and report back.

Comment (by pmav99):

Just tried this with:

- OS: Archlinux
- Linux: 5.0.13
- Python: 2.7.16
- wxPython: 3.0.2.0.1
- wxgtk**3**: 3.0.4-2

and I still can't reproduce the error. The GUI opens without any
tracebacks.

I do get the same warning as @marisn:
{{{
Launching <wxpython> GUI in the background, please wait...
10:37:23: Warning: Mismatch between the program and library build versions
detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1013,wx
containers,compatible with 2.8),
and wxPython used 3.0 (wchar_t,compiler with C++ ABI 1011,wx
containers,compatible with 2.8).

   warnings.warn("wxPython/wxWidgets release number mismatch")
}}}
but this is related to the version mismatch between the installed versions
of wxgtk3 and wxpython, which should not be relevant to the issue at hand.

This might be related to GTK2 vs GKT3 after all. Those of you who can
reproduce this, can you please post wxpython and GTK versions?

In that case, CI should build GRASS for all supported combinations.

Yes, this patch solves most of problems. At least I can start GUI and do
some simple things.

I still see a new error when I try to run some raster modules with GUI

For sure before the r74307 they were absent.
