On second though, this should have Category: UI. Too late for me to change it myself.

The problem comes from the fact that Apple defines unicode codepoints for the arrow keys in one of the private use areas of the unicode standard. So on OS X, the arrow keys produce valid printable characters. Only, OpenTTD is not capable of printing them (and neither should it be since the glyphs for these codepoints are platform dependent).

In that case, such printing should be supressed. Nobody wants to type the uparrow/downarrow glyphs in the openttd chat.

I've done some software archeology myself, to see where that bug was introduced, and going by nightly builds it was introduced somewhere between r7176 and r7194, which is also where the unicode branch was merged in, so that supports what you're saying. I've also measured the characters actually sent on the wire, and they seem to be somewhere within the unicode private usage area as they say.

Emil, if you're taking responsibility for patching this, please post to that effect here, otherwise I'm going to start working on it.
