Creating Topic via email - Reformating the body part of a message

[JoergPalmer]

File / function:
EmailFormat.class.php:365 / _clean_up()

Problem:
The charset parameter is not processed correctly. Towards the end of the function a couple of special characters are replaced in a dedicated way. This must not be done if the text is UTF-8 encoded. Unfortunately this is checked for the capital letter variant 'UTF-8'. In my case the character set came in as 'utf-8' which consequently destroyed the content of the body text.

Solution:
Modify the check to be case insensitive:

// And its 1252 variants
if (strcasecmp($charset, 'UTF-8') !== 0)
