 Test that translations are compiled and installed correctly.
 
 Default encoding in tests is "ascii" and the translation is encoded
 using the "replace" error handler:
 
   $ LANGUAGE=pt_BR hg tip
   abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
   [255]
 
 Using a more accommodating encoding:
 
   $ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
   abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
   [255]
 
 Different encoding:
 
   $ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
   abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
   [255]
 
 #endif
 
 #if gettext
 
 Test keyword search in translated help text:
 
   $ HGENCODING=UTF-8 LANGUAGE=de hg help -k Aktualisiert
   Themen:
   
    subrepos Unterarchive
   
   Befehle:
   
    pull   Ruft \xc3\x84nderungen von der angegebenen Quelle ab (esc)
    update Aktualisiert das Arbeitsverzeichnis (oder wechselt die Version)

 Check Mercurial specific translation problems in each *.po files, and
 tool itself by doctest
 
   $ cd "$TESTDIR"/../i18n
   $ $PYTHON check-translation.py *.po
   $ $PYTHON check-translation.py --doctest
   $ cd $TESTTMP

 Check i18n cache isn't reused after encoding change:
 
   $ cat > $TESTTMP/encodingchange.py << EOF
   > from mercurial import encoding, registrar
   > from mercurial.i18n import _
   > cmdtable = {}
   > command = registrar.command(cmdtable)

   >         ui.write(b'%s\n' % _(b'(EXPERIMENTAL)'))
   > EOF
