convert

int convert(
    const std::string & source,

If a character cannot be represented in outEncoding, defaultChar is used instead. Returns the number of encoding errors (invalid byte sequences in source).

int convert(
    const void * source,
    int length,
    std::string & destination,
    Transform trans
);

Converts the source buffer from inEncoding to outEncoding and appends the result to destination. Every character is passed to the transform function. If a character cannot be represented in outEncoding, defaultChar is used instead. Returns the number of encoding errors (invalid byte sequences in source).
