ECMAScript requires that \u00A0 (the non-breaking space character) be treated
like other white space in program source. Our engine generates a syntax error:
js> eval("2\u00A0+3")
15: SyntaxError: illegal character:
15: 2Ý+3
15: .^
This should print 5.

This is most easily fixed by changing entry 0xA0 of js_Y[] in jsstr.c from 14 to
2.

Same question as for bug 23612: will changes to js_Y break the dependent regexp
classification?

Same answer as for bug 23612: A \s in a regexp should recognize \u00A0 inside a
target string as white space. Fixing the table would fix regexps as well. We
might want to add a test case.
