Re: [tlug] unicode and Perl- how to pass command lineunicode arguments

[Neil Bortnak <nbortnak@example.com>]

Hi David,

Did you ever get your unicode in m// or s/// problem worked out? I
didn't see a solution anywhere in the thread. 

Constructs like:

s/日本語/英語/
m/日本語/

seem to work fine for me in the middle of the program. I'm using "use
utf8;" as per normal, so I'm in a bit of wonderment as to why it doesn't
work for you. If you want me to have a boo at your code to see if we can
fix it, send me an off-list mail.

Neil
