Hello,
playing around with the 2.3-beta1 I noticed that some characters in posts or pages in a
<pre>-Tag are converted to html-entities, which could be bad in some cases. In prior 2.2.2 it works good. I discoverd it while posting my GPG Key, which works better when its not altered ;)
e.g.
2x5 becomes 2×5
-----BEGIN PGP PUBLIC KEY BLOCK----- becomes —–BEGIN PGP PUBLIC KEY BLOCK—–
good function in normal text, but not in <pre>.
I don't know how to file bugs, so maybe someone can reproduce it and find the right words to submit the bug.
