Switch of UTF-8 Flag Before Using `Encode::from_to()`

[gflohr]

The method Locale::RecodeData::Encode::_recode() calls Encode::from_to() which requires its first argument to have the utf-8 flag switched off. Historically that was possible by the bytes pragma but that no longer works. Instead, switch the flag off explicitely.

Otherwise, the method throws an exception "Wide character /include/path/Locale/RecodeData/_Encode line 46".

Also check for other occurences of the bytes pragma which is now deprecated.
