U+2060: Word Joiner

Some scripts have places that are naturally a word boundary, but should not be for some particular instance. For that purpose Unicode provides the WJ (Word Joiner) special character at codepoint U+2060 which you insert wherever you don't want a word boundary:

encoding form	Endianness	S0	S1	S2	S3
UTF-32	be	0x00	0x00	0x20	0x60
	le	0x60	0x20	0x00	0x00
UTF-16	be	0x20	0x60
	le	0x60	0x20
UTF-8		0xE2	0x81	0xA0

But you'd be surprised how few programs support this vital unicode feature. Try getting Japanese to wrap between words in a .NET Winforms control.
