NAME
UTF8::R2 - provides minimal CP932NEC I/O subroutines by short name
SYNOPSIS
use CP932NEC::R2;
@result = mbeach($utf8str)
$result = mbtr($utf8str, 'ABC', 'XYZ', 'cdsr')
$result = iolen($utf8str)
$result = iomid($utf8expr, $offset_as_cp932x, $length_as_cp932x, $utf8replacement)
@result = ioget(FILEHANDLE)
$result = ioput(FILEHANDLE, @utf8str)
$result = ioputf(FILEHANDLE, $utf8format, @utf8list)
@result = iosort(@utf8str)
$result = $utf8str =~ $mb{qr/$utf8regex/imsxogc}
$result = $utf8str =~ s<$mb{qr/before/imsxo}><after>egrMBCS SUBROUTINES for SCRIPTING
It is useful to treat regex in perl script as code point of UTF-8. Following subroutines and tied hash variable provide UTF-8 semantics for us.

// or m// or qr// $mb{qr/$utf8regex/imsxogc} not supports metasymbol \X that match grapheme
not support range of codepoint(like an "[A-Z]")
not supports POSIX character class (like an [:alpha:])
(such as \N{GREEK SMALL LETTER EPSILON}, \N{greek:epsilon}, or \N{epsilon})
not supports character properties (like \p{PROP} and \P{PROP})

If you use following subroutines then I/O encoding convert is automatically. These subroutines provide CP932NEC octets semantics for you.
