Since you asked..
s means search and replace, the forward slash starts the match.
- match FOO in word boundaries ( \< and \> ), followed by
- At least one character that is not alphanumeric or underscore ( \W\+ )
- Then look for any characters ( .* ) in word boundaries.
- Mark these characters by using \( and \) so that we can reproduce it later using \1
- Then this is followed by non alphanumeric or underscore characters, followed by
- BAR in word boundaries
- / marks the end of the match
- \1 reproduces the marked characters
- / marks the end of the search and replace

RKCVTHAN(3) Library Functions Manual RKCVTHAN(3)
NAME
RkCvtHan / RkwCvtHan - convert double-width symbols, alphanumeric characters, hiragana, and katakana to single-width characters
SYNOPSIS
#include <canna/RK.h>
int RkCvtHan(dst, maxdst, src, srclen)
unsigned char *dst;
int maxdst;
unsigned char *src;
int srclen;
int RkwCvtHan(dst, maxdst, src, srclen)
wchar_t *dst;
int maxdst;
wchar_t *src;
int srclen;
DESCRIPTION
RkCvtHan converts the srclen bytes of double-width symbol, alphanumeric characters, hiragana, and katakana data to single-width characters,
starting at the area src. A null character in src is not interpreted as the end of the string. The conversion result is stored in the
area dst. Characters that are not subject to conversion are copied as they are. The conversion result is truncated to adjust to character
boundaries in the EUC code when its byte length exceeds maxdst -1. dst is padded with null characters at the end if possible. EUC code is
used to represent both src and dst.
RkwCvtHan is the wchar_t version of RkCvtHan. Arguments which specify the length are regarded as they count the character length instead
of byte length.
NULL can be specified in dst. NULL overrides the entire conversion result.
RETURN VALUE
This function returns the byte length (or character length for RkwCvtHan) of the conversion result, or returns 0 if the value of maxdst is
invalid.
