Description

The following code:https://3v4l.org/3cnGD/rfc#vgit.master

<?phpechomb_detect_encoding('abc','UTF8, ASCII');

Resulted in this output:

Fatal error: Uncaught ValueError: mb_detect_encoding(): Argument #2 ($encodings) contains invalid encoding "UTF8"

But I expected this output instead:

UTF-8

This is a regression, seehttps://3v4l.org/3cnGD

And this works if the list is given as an array:https://3v4l.org/lVva0/rfc#vgit.master
