fixed unescapeString in the same manner as google chrome.

Trailing space is unicode terminator, to be deleted.
'hei\DF en' -> 'heisen'
'hei\00DF en' -> 'heisen'
'hei\0000DF en' -> 'heisen'

Six characters of the unicode without terminator.
'hei\0000DFen' -> 'heisen'

Non hex-character is unicode terminator, to be passed.
'hei\DFt' -> 'heist'
