Question

How can I check whether bytes in a byte array are Unicode characters?

main probleme:

android 4.2 new String(bytes) remove unicode chars from my String: [\uFFFD]

I need a workaround for this.

Answer 1

return Charset.forName("UTF-8").newEncoder().canEncode(string);

UPDATE: You didn’t pass a Charset to new String(bytes), so it just assumes you’re using the default charset. Instead, do e.g. new String(bytes, "UTF-8").
