convert


Description:

public string convert (string str, ssize_t len, string to_codeset, string from_codeset, out size_t bytes_read = null, out size_t bytes_written = null) throws ConvertError

Converts a string from one character set to another.

Note that you should use iconv for streaming conversions. Despite the fact that bytes_read can return information about partial characters, the g_convert_... functions are not generally suitable for streaming. If the underlying converter maintains internal state, then this won't be preserved across successive calls to convert , convert_with_iconv or convert_with_fallback. (An example of this is the GNU C converter for CP1255 which does not emit a base character until it knows that the next character is not a mark that could combine with the base character.)

Using extensions such as "//TRANSLIT" may not work (or may not work well) on many platforms. Consider using to_ascii instead.

Parameters:

str

the string to convert.

to_codeset

name of character set into which to convert str

from_codeset

character set of str.

bytes_read

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 str.length if there were partial characters at the end of the input. If the error ILLEGAL_SEQUENCE 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).

len

the length of the string in bytes, or -1 if the string is nul-terminated (Note that some encodings may allow nul bytes to occur inside strings. In that case, using -1 for the str.length parameter is unsafe)

Returns:

If the conversion was successful, a newly allocated buffer containing the converted string, which must be freed with g_free. Otherwise null and throws will be set.
