Unicode Transformation Format of 32-bit unit width, whose encoding space

refers to the Unicode's codeset standard. This encoding scheme wasn't

identical to UCS-4 because the code space of Unicode were limited to

Unicode Transformation Format of 16-bit unit width. It's worth a note

that UTF-16 is no longer the same specification as UCS-2 because the

surrogate mechanism has been introduced since Unicode 2.0 and

UTF-16 now refers to a 21-bit code space.

As you see the name is derived from an abbreviation of Extended UNIX Code
|
|
Packed Format for Japanese, this encoding is mostly used on UNIX or
|
|
alike platforms. The original encoding scheme, Extended UNIX Code, is
|
|
designed on the basis of ISO 2022.
|

</seg>
|
|
<seg>
|
|
The character set referred to by EUC-JP is different to IBM932 / CP932,
|
|
which are used by OS/2® and Microsoft® Windows®.
|
|
For information interchange with those platforms, use EUCJP-WIN instead.

Shift_JIS was developed in early 80's, at the time personal Japanese word
|
|
processors were brought into the market, in order to maintain
|
|
compatibilities with the legacy encoding scheme JIS X 0201:1976.
|
|
According to the IANA definition the codeset of Shift_JIS is slightly
|
|
different to IBM932 / CP932. However, the names "SJIS" / "Shift_JIS" are
|
|
often wrongly used to refer to these codesets.
|
|
</seg>
|
|
<seg>For the CP932 codemap, use SJIS-WIN instead.</seg>

While this "encoding" uses the same encoding scheme as EUC-JP,
|
|
the underlying character set is different. That is, some code points map
|
|
to different characters than EUC-JP.
