Where can I find documentation about this $KCODE global var and the "s" thing
after each regexp? What does the s exactly mean?
Do I have to put it only in regexps with japanese characters or any regexp? I
tried both and saw no difference.
When using Regexp.new to construct the regular expression how can I set the s
to the end of it??
sorry for so many questions but I don't seem to find any docs about these
options.

The encoding seems to be Shift_JIS. You have to specify encoding
before you make regular expression matching. Put s after every
regular expression.
$KCODE="sjis" # to make p work right
p s = "鞄"
p l = "行"
p l =~ /s/s
puts "#{$`}<<#{$&}>>#{$'}"
p "#{$`}<<#{$&}>>#{$'}"
p s =~ /l/s
Just one question, it seems to me that I can make two different things to
allow Regexp's to handle multibyte Shift_JIS strings. One is to set the
$KCODE global variable to "sjis" and the other one is to use the "s" modifier
when constructing the regular expresion.
The question is do I use only one of the two methods or shall I use the "s"
modifier even if I set $KCODE to "sjis"??
My testing tells me that only setting the $KCODE global var is enough to get
Shift_JIS strings and Regexp's to work correctly but I just want to make
sure.
thanks,
Horacio

Thanks a lot... this seems to work ok.
Where can I find documentation about this $KCODE global var and the "s"
thing after each regexp? What does the s exactly mean?
