Function locale_from_utf8

pub fn locale_from_utf8(
    utf8string: impl IntoGStr,
) -> Result<(Slice<u8>, usize), CvtError>

Converts a string from UTF-8 to the encoding used for strings by the C runtime (usually the same as that used by the operating system) in the current locale. On Windows this means the system codepage.

The input string shall not contain nul characters even if the @len argument is positive. A nul character found inside the string will result in error ConvertError::IllegalSequence. Use g_convert() to convert input that may contain embedded nul characters.

utf8string

a UTF-8 encoded string

len

the length of the string, or -1 if the string is nul-terminated.

Returns

     A newly-allocated buffer containing the converted string,
     or [`None`] on an error, and error will be set.

bytes_read

location to store the number of bytes in the input string that were successfully converted, or None. Even if the conversion was successful, this may be less than @len if there were partial characters at the end of the input. If the error ConvertError::IllegalSequence occurs, the value stored will be the byte offset after the last valid input sequence.
