This avoids very common text encoding problems.

You have not avoided the very common test writing problem! 😄

I had also not avoided the very common "my change does not have any effect and a test would have shown that" problem 😓

Now it’s fixed: our plain text filter actually detects the charset from the BOM and uses UTF-8 by default.

if(handler.takesACharset && ((charset == null) || (charset.isEmpty()))) {
byte[] charsetBuffer = new byte[CHARSET_DETECTION_FALLBACK_BUFFERSIZE];
int offset = readIntoBuffer(input, CHARSET_DETECTION_FALLBACK_BUFFERSIZE, charsetBuffer);
BOMDetection bom = CSSReadFilter.detectCharsetFromBOM(charsetBuffer, CHARSET_DETECTION_FALLBACK_BUFFERSIZE);

I’m pretty sure this is 100% wrong. That method detects an encoding from the representation of the string @charset. It is also gloriously misnamed as it has nothing to do with a BOM. 😀
