Legacy Encodings support in Opera Presto 2.7

Although Opera works with the Unicode character set and its character encodings of UTF-16 and UTF-8, most text on the Internet is encoded in legacy encodings, for instance:

Opera handles this by detecting the character encoding used, and converting it to UTF-16. The user has three options for how to handle these pages.

Opera Presto includes support for Unicode 5.2 character properties (class, casing, bidirectionality, mirroring, normalization) from 5.0.

Big5-HKSCS support for the HKSCS-2008 encoding standard has been updated.

Charset CP51932 is now implemented as an alias of euc-jp.
