unicode support

unicode support

[Dima]

Hi.
   Did something change from guile 1.8.x to 2.0 with regards to unicode support.

I have a script that has strings written on russian without much care, and it does not work on 2.0.

I want to make sure whether there are changes in guile or something else.

Thanks, regards,
  Dima.

Hi, dmitriy. Try to add this line to head your scripts

(setlocale LC_ALL "")
(set-port-encoding! (current-input-port) "utf-8")
(set-port-encoding! (current-output-port) "utf-8")

Also, note that by default the source file is expected to be
UTF-8-encoded.

You can use a different encoding, but then the file needs to contain a
‘coding:’ cookie (info "(guile) Character Encoding of Source Files").

The 'setlocale' call is indeed important.

The next two lines shouldn't be needed, and would cause breakage on
non-utf8 locales.

Yes, it is. And let me emphasize this again for any non latin-1 users.
Because it's so common that I was asked by others frequently.
My projects are heavily using CJK, so I always put it under shebang
lines to avoid "????" situation:
------------------------code-----------------------
#! /bin/env guile
!#
(setlocale LC_ALL "")
------------------------end------------------------
Don't forget this ;-)
