### Function

# GLib locale_from_utf8

since: 2.0

#### Declaration

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

#### Description

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.

Available since: 2.0

#### Parameters

`utf8string`

  Type: `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`

  Type: `gssize`

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

`bytes_read`

  Type: `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`

  Type: `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`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: 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.
