This was intended for translating filenames from filesystem charset to the terminal charset. Modern sane platforms use UTF-8 for everything, and on Windows we use unicode APIs, so this is not needed anymore. Remove filename_recode, all uses of it, options and configure checks related to terminal output charset, and code that tries to determine the same.

/* gettext expects the global locale to be set with
|
|
* setlocale(LC_ALL, ""). However doing that would suck for a
|
|
* couple of reasons (locale stuff is badly designed and sucks in
|
|
* general).
|
|
*
|
|
* First, setting the locale, especially LC_CTYPE, changes the
|
|
* behavior of various C functions and we don't want that - we
|
|
* want isalpha() for example to always behave like in the C
|
|
* locale.
|
|
|
|
* Second, there is no way to enforce a sane character set. All
|
|
* strings inside MPlayer must always be in utf-8, not in the
|
|
* character set specified by the system locale which could be
|
|
* something different and completely insane. The locale system
|
|
* lacks any way to say "set LC_CTYPE to utf-8, ignoring the
|
|
* default system locale if it specifies something different". We
|
|
* could try to work around that flaw by leaving LC_CTYPE to the C
|
|
* locale and only setting LC_MESSAGES (which is the variable that
|
|
* must be set to tell gettext which language to translate
|
|
* to). However if we leave LC_MESSAGES set then things like
|
|
* strerror() may produce completely garbled output when they try
|
|
* to translate their results but then try to convert some
|
|
* translated non-ASCII text to the character set specified by
|
|
* LC_CTYPE which would still be in the C locale (this doesn't
|
|
* affect gettext itself because it supports specifying the
|
|
* character set directly with bind_textdomain_codeset()).
|
|
*
|
|
* So the only solution (at least short of trying to work around
|
|
* things possibly producing non-utf-8 output) is to leave all the
|
|
* locale variables unset. Note that this means it's not possible
|
|
* to get translated output from any libraries we call if they
|
|
* only rely on the broken locale system to specify the language
|
|
* to use; this is the case with libc for example.
|
|
*
|
|
* The locale changing below is rather ugly, but hard to avoid.
|
|
* gettext doesn't support specifying the translation target
|
|
* directly, only through locale.
|
|
* The main actual problem this could cause is interference with
|
|
* other threads; that could be avoided with thread-specific
|
|
* locale changes, but such functionality is less standard and I
|
|
* think it's not worth adding pre-emptively unless someone sees
|
|
* an actual problem case.
