Tsukasa OI 96ba6afd47 Fix copying on supplementary plane characters ...

pdf.js had a problem when copying characters on supplementary planes
(0xPPXXXX where PP is nonzero).  This is because certain methods of
PartialEvaluator use classic String.fromCharCode instead of ES6's
String.fromCodePoint.

Despite the fact that readToUnicode method *tried* to parse out-of-UCS2
code points by parsing UTF-16BE, it was inadequate because
String.fromCharCode only supports UCS-2 range of Unicode.
