/*

* Convert a string between UTF-8 and the locale's charset.
|
|
* Invalid bytes are replaced by '#', and characters that are
|
|
* not available in the target encoding are replaced by '?'.
|
|
*
|
|
* If the locale's charset is not set explicitly then it is
|
|
* obtained using nl_langinfo(CODESET), where available, the
|
|
* environment variable CHARSET, or assumed to be US-ASCII.
|
|
*
|
|
* Return value of conversion functions:
|
|
*
|
|
* -1 : memory allocation failed
|
|
* 0 : data was converted exactly
|
|
* 1 : valid data was converted approximately (using '?')
|
|
* 2 : input was invalid (but still converted, using '#')
|
|
* 3 : unknown encoding (but still converted, using '?')
