Detailed Description

Exception thrown on encoding/decoding failure.

Most UTF8 functions will throw an exception if input string is not a valid encoding.

So far there are two possible causes:

• invalid_utf8 if the string is not a valid UTF-8 encoding
• invalid_char32 if the string is not a valid UTF-32 codepoint.

You can handle a utf8::exception using code like this:

//...
catch (utf8::exception& e) {
  if (e.code == utf8::exception::invalid_utf8) {
    // do something
  }
}

or you can simply use the exception message:

//...
catch (utf8::exception& e) {
  cout << e.what() << endl;
}
