Known Unicode Encodings

Out of all the encodings listed on the encodings page, only a handful are known to be Unicode Encodings. These are as follows:

• UTF-7

• UTF-7-IMAP

• UTF-8

• UTF-16 (All Endiannesses)

• UTF-32 (All Endiannesses)

• GB18030

• CESU-8

• MUTF-8

• WTF-8

• UTF-1

• UTF-EBCDIC

When the encoding is known at compile time (e.g., it is just a plain object), it contains a is_unicode_encoding type member that is set to std::true_type. Otherwise, it is left off. This is detected by ztd::text::contains_unicode_encoding and ztd::text::is_unicode_encoding.

If you know of any others, please let us know!
