Redmine

When attempting to place a Unicode literal in the wiki, the preview looks fine, but after saving the page, the literal has been replaced by a single questionmark.

The odd thing is, it seems to go fine for "lower" Unicode characters, since greek literals (for instance: µ (micro sign)) work fine. It's the ♥ (black heart suit) that's giving me a headache here.

Using HTML character entities is a suitable solution outside <code> blocks, but using Unicode literals inside these blocks is necessary, as HTML character entities get rendered differently (namely, you end up with &#x2665; and not ♥)
