EasyPopulate 4.0 Support Thread

[mesnitu]

$category_delimiter (not categories) is defined at the top of easypopulate_4.php.

This code is a bit "mixed up" here from attempts to fix the various issues dealing with multi-byte languages.

My use of EP4 is with full export and now with bookx files. And in those situations I don't see a reason to re-assign that variable upon categories.
But possibly is related with attributes and stuff that I never used.
Or someother stuff that I'm not seeing .
