Re: [PHP] mb_convert_encoding converting to ASCII instead of UTF-8
A little additional info: The "ASCII to ASCII" case for "Minnie=Mouse"
is merely because the UTF-8 encoding for "Mouse" is the same as the
ASCII encoding for "Mouse", and mb_detect_encoding is matching on ASCII
before UTF-8. So that's not an issue.
But, the "UTF-8 to ASCII" case for "Minnie=Miņoso" is still (seemingly)
screwy.
