It looks like you have ASCII but the encoding specifies unicode. If the
way the text is encoded does not match the contents, you will get this.
Encoding must be 00 or 01. If it is 00 you must have ascii characters,
if it is 01 you must have unicode. If you use 01 with ascii characters
you will see the problem that you have.
You really need to determine whether the song requires unicode or not.
If it only uses standard ascii characters you can encode with ascii,
other wise you should use Unicode.
Here is my code that does this in java. Note that for ID3v2.3 only
encoding types 01 and 1 are valid("ISO-8859-1" and "UTF16"). the other
two values are valid for ID3V2.4, which is not widely supported, so I do
not recommend using them.
static final String[] ENC_TYPES = {"ISO-8859-1", "UTF16",
"UTF-16BE", "UTF-8"};
// Attempt to encode in encoding 0, if not possible use encoding 1
static public byte [] encodeString(String source, byte[] encodingB)
throws UnsupportedEncodingException {
byte [] result = source.getBytes(ENC_TYPES[encodingB[0]]);
if (encodingB[0] == 0) {
String checkResult = new
String(result,ENC_TYPES[encodingB[0]]);
if (!source.equals(checkResult)) {
encodingB[0] = 1;
result = source.getBytes(ENC_TYPES[encodingB[0]]);
}
}
return result;
}
