"No-Break Space" character code in Unicode is 0xA0 and &nbsp; is named 
entity reference which usually refers to that character. So instead of 
named reference, generating of which is troublesome in XSLT, you can use 
numeric character reference &#x_A_0; or &#0_1_6_0; (the same), that's it.

Document encoding doesn't matter, numeric character references refer to 
Unicode character code. It's safe, don't worry, everybody using &#1_6_0; 
instead of &nbsp;.
