Bug: htmlentities messes code blocks

[Carlos]

Greek characters are unicode supported. If entered as regulart text, they make no difference than other text.
If entered in a <code> block they are presented with their entity form. This results to

Code:

π = 3.14
φ = 1.62

instead of
[...]

You mean in the source code of a page?
I think that html entities are generated in the page content not only between <code> and </code> tags, but everywhere. It happens also with characters like á (&aacute, ä (&auml, etc.

Not a serious problem, as pages are rendered equally by the browser, the user doesn't notice.

...But anyway, I like your suggested patch: the page's source code is more readable if it is in German, French, Spanish, etc. (and I believe it wouldn't break anything)
