g_locale_from_utf8 (
  const gchar* utf8string,
  gssize len,
  gsize* bytes_read,
  gsize* bytes_written,
  GError** error


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.


utf8string const gchar*

A UTF-8 encoded string.

 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.
len gssize

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

bytes_read gsize*

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.

 The argument will be set by the function.
 The argument can be NULL.
bytes_written gsize*

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

 The argument will be set by the function.
 The argument can be NULL.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: An array of guint8
     A newly-allocated buffer containing the converted string,
     or `NULL` on an error, and error will be set.
 The length of the array is in the bytes_written argument.
 The caller of the function takes ownership of the data, and is responsible for freeing it.
