Function glib::locale_to_utf8

pub fn locale_to_utf8(opsysstring: &[u8]) -> Result<(GString, usize), CvtError>

Converts a string which is in the encoding used for strings by the C runtime (usually the same as that used by the operating system) in the [current locale][setlocale] into a UTF-8 string.

If the source encoding is not UTF-8 and the conversion output contains a nul character, the error ConvertError::EmbeddedNul is set and the function returns None. If the source encoding is UTF-8, an embedded nul character is treated with the ConvertError::IllegalSequence error for backward compatibility with earlier versions of this library. Use convert() to produce output that may contain embedded nul characters.

opsysstring

a string in the encoding of the current locale. On Windows this means the system codepage.

Returns

The converted string, or None on an error.

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.

bytes_written

the number of bytes stored in the output buffer (not including the terminating nul).
