a UTF-8 encoded string
the length of the string, or -1 if the string is nul-terminated.
location to store the number of bytes in the input string that were successfully converted, or %NULL. 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 %G_CONVERT_ERROR_ILLEGAL_SEQUENCE occurs, the value stored will be the byte offset after the last valid input sequence.
A newly-allocated buffer containing the converted string, or %NULL on an error, and error will be set.
GException on failure.
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]setlocale. 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 %G_CONVERT_ERROR_ILLEGAL_SEQUENCE. Use g_convert() to convert input that may contain embedded nul characters.
