-------------------------------------------------+-------------------------
 The main GUI (g.gui) in 7.0.4RC1 32bit fails to start because of non-ascii
 characters in `g.version -rge`, namely in `libgis_date` entry which is
 `"2015-12-24 16:07:44 +0100 (Ä?t, 24 12 2015) "` (I assume "Út", i.e. date
 with locales instead of some ASCII). The tested computer has some US
 locales.

 Perhaps wxGUI should deal with that by some different handling (I don't
 know what `charmap` is and how computes encoding influences that) or by
 ignoring all errors and not showing the version (but maybe the version is
 needed also elsewhere).

 7.1 (trunk) works.
