Encoding

Hi
Source of the previous problem was the encoding.

test.rb:
# encoding: US-8859-1
p __ENCODING__ # says UTF-8 !?!???
...gsub(/ü/,...) # failure

The sourcefile is ISO-8859 (because of bad editor) - (( I want to solve the
ruby-problem, but if we have vi-experts: after :set enc=utf8 :x the file is
still iso?! ))

How can I input an Umlaut,
or can get rid of "invalid multibyte char (utf8)"

Datafile is in utf-8, so the error comes from the source.
Google tells much of Ruby 1.9, but all that didnt help.

Thank you
Berg

[snip]

Save your source as UTF-8.

but if we have vi-experts [snip]

Really...?!?
Search for "vim save with new file encoding" or similar.

No, what it actually should say is

  unknown encoding name: US-8859-1 (ArgumentError)

Please, do not post pseudo code with typos in it (it's ISO-8859-1),
but actual working code that we can simply copy and paste to verify
your problem.

...gsub(/ü/,...) # failure

I can not reproduce a failure.

Again: please show the *actual* code and the specific error message.

Regards,
Marcus

Hi
thats because I cant copy&paste...

x.rb:
!#/usr/bin/ruby
# Encoding: xxx
# encoding=xxx
p __ENCODING__
   # shows "#<Encoding:UTF-8>" (and no error)
   # Ruby version 2.3.0
Sure you'll get the same results...
./x.rb

irb works as expected, mri not.

that's ... strange ...

x.rb:
!#/usr/bin/ruby
# Encoding: xxx
# encoding=xxx
p __ENCODING__
   # shows "#<Encoding:UTF-8>" (and no error)
   # Ruby version 2.3.0

No! I already said it works fine for me (using 2.3.0).

Note that the shebang line in your code is wrong;
you really shouldn't expect us to try and figure out what
your problem is when you are too careless or lazy to post
the correct code.

And get a proper mail client and/or editor or whatever it is
that doesn't allow you to copy&paste or you'll never be able
to work productively.
