Convert Encoding Format of a String

You can manually convert a string from one encoding to another (UTF-8, Unicode, or locale machine encoding) using the lr_convert_string_encoding function with the following syntax:

lr_convert_string_encoding(char * sourceString, char * fromEncoding, char * toEncoding, char * paramName)

The function saves the result string (including its terminating NULL) in the third argument, paramName. It returns a 0 on success and -1 on failure.

The format for the fromEncoding and toEncoding arguments are:

In the following example, lr_convert_string_encoding converts "Hello world" from the system locale to Unicode.

Action()
{
    int rc = 0;
    unsigned long converted_buffer_size_unicode = 0;
    char               *converted_buffer_unicode = NULL;
    rc = lr_convert_string_encoding("Hello world", NULL, LR_ENC_UNICODE, "stringInUnicode");
    if(rc < 0)
    {
        // error
    }
return 0;
}

In the replay log, the output window shows the following information:

Output:
Starting action Action.
Action.c(7): Notify: Saving Parameter "stringInUnicode = H\x00e\x00l\x00l\x00o\x00 \x00w\x00o\x00r\x00l\x00d\x00\\x00"
Ending action Action.

The result of the conversion is saved to the paramName argument.
