@jhass Maybe, I'll later check if that's valid for iconv. |

I don't think it is - at least it's behind a |

Oh - Seems libiconv isn't used and iconv is built into the glibc. |

We have
IO#set_encodingwhich accepts an encoding. If it's UTF-8 there's nothing to do, because IO is assumed to be UTF-8 by default (regarding text). The current comparison is case sensitive, but in some cases the encoding can come with other cases (like in #6353). So to avoid using iconv, which should be slower then just doing it in Crystal (and also a bit redundant), I added a case insensitive comparison.Update: includes tests.
