Hi,

does this no longer work?

--------------------
#!/usr/bin/env ruby
# -*- coding: UTF-8 -*-

puts $KCODE
puts "äöüÄÖÜß"
--------------------

I tried it with Ruby 1.8.2 and 1.9, Debian Linux.
What do I miss?

That didn't work for me under Windows.

Can you add -Ku to the shebang line? That did work for me.

(Outputs "None" and "äöüÄÖÜß".)

That's exactly the problem. Only the first of these both works:

#!/usr/local/bin/ruby -Ku
#!/usr/bin/env ruby -Ku

So, I came to
<http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-cor....
But it doesn't seem to work here and I cannot find anything
in the source code.

You forgot to define the meaning of 'no longer works':

- What precisely do you mean by 'it works'?

- What is the reference to compare to?

- Did you switch to a different terminal emulation or change your
terminal emulation's settings since 'it works'?

I wrote the scriptlet to deppian.rb; ruby deppian.rb results in:

NONE
äöüÄÖÜß

NONE
äöüÃÃÃÃ

or even more alien results. The former is for a utf-8 terminal, the
latter for an iso-8859-1 terminal.

When in doubt *set* $KCODE explicitly.

Note that the above quote has been converted from utf-8 to iso-8859-1
to avoid artefacts resulting from mixed use of iso-10646 and iso-8859
- fortunately 'wanderlust' does not choose the charset without askign
the user to accept the choice.

Sorry, that was not actually elaborate. Now I think it
never worked at all.

In the meantime I received an answer in ruby-core and it
seems Matz just _planned_ to implement it but didn't have
the time yet.

The problem arises when my program is run on SuSE Linux
where the default encoding is UTF-8.

A better way to test in which encoding you reside is:

"Ã?" =~ /./
puts $&.length

This gives 1 in `None' and 2 in `UTF-8'.

This has no influence on how the source code is read. The
string "Ã" produces an error when `ruby -Ku' is called.

Of course I should have written "\xc3\xa4" and "\xc3".

Sorry again for the noise.

Is this the only way to handle strings UTF-8 in ruby?

(Butyou should use ruby -Ku then).But some UTF-8 things are a bit weird. E.g. the length of an UTF-8String is the length of its bytes not the number of characters, so Ihad to write my own utf-8_length routine.regards,Brian-- http://ruby.brian-schroeder.d... instrument chords: http://chordlist.brian-sch...

You never know what happens to your mail in a thousand
