GRASS 7.0 RC1 wxGUI: fails to launch in Spanish locale (UnicodeEncodeError)

[santipardo]

With Spanish locale (es_ES.UTF-8), GRASS 7.0 RC1 doesn't launch. I have launched it perfectly in the same installation with locale en_US-UTF-8. The problem is happening since beta 4.0.

CONF:

Linux Mint 17.1
$ locale | grep LANG
LANG=es_ES.UTF-8

I encoded the string in r64335 to the encoding set during the startup. I am not sure if that solves the problem, needs testing.

[santipardo]

I am afraid the problem is yet there...

(Working again perfectly with locale en_US.UTF-8)

[annakrat]

I changed it only in trunk (grass71). Can you test it there?

Tested after compiling from trunk:

svn co https://svn.osgeo.org/grass/grass/trunk

That change is bogus. The string should be a str (byte string), not unicode, so calling .encode() on it is meaningless. Reverted in r64364.

The error appears to arise from r41856 passing unicode=True to gettext.install(), meaning that translated strings are returned as unicode values which then end up being converted to strings using the default encoding. Fixed in r64366.

A similar mistake exists in r59652, fixed in r64367

Now the GUI opens and it's perfectly working in locale Spanish. Thanks!!!

Reopening the ticket because it needs to be backported to relbr70 before closing.

I tried to backport r64367 to relbr70 in r64369. Unfortunately grass.py in trunk differs from relbr70 too much regarding language settings. Does anybody know more about that? I hesitate to backport the diff completely in hard freeze.

Anyway, please, could you try also recent GRASS 70 release branch? It should have been fixed there too.

OK, I took liberty to sync set_language() functions with try. Please try out r64370.

[santipardo]

Recompiled from r64370 and working now. The /etc/VERSIONNUMBER doesn't update, it remains "7.0.0svn r64369" (I don't know if there's a little bug here, or it's only a problem in my system).

But it works!

you need to run configure script to update revision number.

But it works!

Thanks for testing, closing ticket.
