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 g_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).
