Obtains the character set used by the console attached to the process, which is suitable for printing output to the terminal.
Usually this matches the result returned by get_charset, but in environments where the locale's character set does not match the encoding of the console this function tries to guess a more suitable value instead.
On Windows the character set returned by this function is the output code page used by the console associated with the calling process. If the codepage can't be determined (for example because there is no console attached) UTF-8 is assumed.
The return value is true if the locale's encoding is UTF-8, in that case you can perhaps avoid calling convert.
The string returned in
