NAME

CP932::R2 - provides minimal CP932 I/O subroutines by short name

SYNOPSIS

            

              
              
use CP932::R2;
  @result = mbeach($utf8str)
  $result = mbtr($utf8str, 'ABC', 'XYZ', 'cdsr')
  $result = iolen($utf8str)
  $result = iomid($utf8expr, $offset_as_cp932, $length_as_cp932, $utf8replacement)
  @result = ioget(FILEHANDLE)
  $result = ioput(FILEHANDLE, @utf8str)
  $result = ioputf(FILEHANDLE, $utf8format, @utf8list)
  @result = iosort(@utf8str)
  $result = $utf8str =~ $mb{qr/$utf8regex/imsxo}
  $result = $utf8str =~ m<$mb{qr/$utf8regex/imsxo}>gc
  $result = $utf8str =~ s<$mb{qr/before/imsxo}><after>egr
            
          

MBCS 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.

MBCS SUBROUTINES for I/O

If you use following subroutines then I/O encoding convert is automatically. These subroutines provide CP932 octets semantics for you.
