 The intention of these functions is to provide an alternative which is
 more compliant with the current implementation of GNU gettext. Unlike
 '''gettext(), which returns strings encoded with the same codeset used in
 the translation file''', lgettext() will return strings encoded with the
 preferred system encoding, as returned by locale.getpreferredencoding().

 .gettext() method rather than to the .lgettext() method.

 > Try r64834:

 {{{
 #!python
 import gettext
 gettext.install('grasslibs', os.path.join(os.getenv("GISBASE"), 'locale'))
 import __builtin__
 __builtin__.__dict__['_'] = __builtin__.__dict__['_'].im_self.lgettext
 }}}

 This solves the problem but the fix is yet another reason for me to
 believe that translation function should be explicitly imported and
 changing buildins, explicit or hidden, should be avoided. Compare the code
 above with the code in GUI (r57219 and r57220):

 {{{
 #!python
 # gui/wxpython/core/utils.py
 # _ intended to be used also outside this module
 try:
     # intended to be used also outside this module
     import gettext
     _ = gettext.translation('grasswxpy',
 os.path.join(os.getenv("GISBASE"), 'locale')).ugettext
 except IOError:
     # using no translation silently
     def null_gettext(string):
         return string
     _ = null_gettext
 }}}

 Please see the further discussion in #2425.
