understand: first of all, the application locale is changed - note that this
will affect many of standard C library functions such as printf() or strftime().

- wxGetTranslation and the
- _ macro). It is used if AddCatalog cannot find any
+ wxGetTranslation() and the
+ _() macro). It is used if AddCatalog cannot find any
catalog for current language: if the language is same as source code language,
then strings from source code are used instead.
-
- @e msgIdCharset lets you specify the charset used for msgids in sources
+ @a msgIdCharset lets you specify the charset used for msgids in sources
in case they use 8-bit characters (e.g. German or French strings). This
argument has no effect in Unicode build, because literals in sources are
Unicode strings; you have to use compiler-specific method of setting the right
charset when compiling with Unicode.
-
By default (i.e. when you use the first form), msgid strings are assumed
to be in English and written only using 7-bit ASCII characters.
-
If you have to deal with non-English strings or 8-bit characters in the source
code, see the instructions in
@ref overview_nonenglishoverview "Writing non-English applications".

looked up under prefix/lang/LC_MESSAGES, prefix/lang and prefix
