Commented Unassigned: Unicode problem [20420]

Hello,

Ajaxmin throws exceptions when minifying a Unicode value:
$.Constant({Static:true , Public:false}, "HIGH_SURROGATE_START", "\ud800");
Error : Invalid hexadecimal escape sequence: "\ud800

It seems to process as a string instead of Unicode.

Thanks in advance for your help.

How about I create a separate error for this condition with a lower severity, so it doesn't show up unless you're analyzing the code or have otherwise bumped the warning threshold up?
