The range from U+E000 to U+F8FF is Private Use, and, thus, in use. There are also usable ranges from U+F900 up to U+FFFF, and beyond. The only big invalid range in UTF-8 encoding, is for the codepoints in the surrogates area: U+D800 to U+DFFF. These are used by UTF-16 to encode codepoints outside the base plane.

I've got a bug report concerning the UTF decoding in HXT. I've copied the source containing the bug from the Haskell Internationalisation Working Group. I guess this source is also used in other projects, e.g. darcs.
My question: Is this really a bug or is it a feature. My knowlege so far was, the intervall from E000 to FFFF is not legal in unicode.

Subject: Bug in the HXT: Data.Char.UTF8.decodeOne Date: Sunday 10 June 2007 07:40 From: PHO <phonohawk@ps.sakura.ne.jp> To: hxmltoolbox@fh-wedel.de
Hello,
I've found a bug in Data.Char.UTF8.decodeOne that it fails to decode UTF-8 letters from U+E000 to U+FFFF. Here is the patch:
{ hunk ./src/Data/Char/UTF8.hs 248 - | b1 < 0xEE = decodeOne_threebyte bs + | b1 < 0xF0 = decodeOne_threebyte bs } --------------------------------------------------------------
here is the source http://darcs.fh-wedel.de/hxt/src/Data/Char/UTF8.hs
Any suggestions?
