This seems to be a bug??

I try to read the source code。

func newRecognizer_8859_2(language string, ngram *[64]uint32) *recognizerSingleByte {
	return &recognizerSingleByte{
		charset:          "ISO-8859-2",
		hasC1ByteCharset: "windows-1250",
		language:         language,
		charMap:          &charMap_8859_2,
		ngram:            ngram,
	}
}

func newRecognizer_8859_2_cs() *recognizerSingleByte {
	return newRecognizer_8859_1("cs", &ngrams_8859_2_cs)
}
func newRecognizer_8859_2_hu() *recognizerSingleByte {
	return newRecognizer_8859_1("hu", &ngrams_8859_2_hu)
}
func newRecognizer_8859_2_pl() *recognizerSingleByte {
	return newRecognizer_8859_1("pl", &ngrams_8859_2_pl)
}
func newRecognizer_8859_2_ro() *recognizerSingleByte {
	return newRecognizer_8859_1("ro", &ngrams_8859_2_ro)
}

According to the function naming rule，maybe

func newRecognizer_8859_2_cs() *recognizerSingleByte {
	return newRecognizer_8859_2("cs", &ngrams_8859_2_cs)
}

You're very careful. I think you're right
