Support for UTF-8

[paronsson]

Hi,

reflex & try-reflex is really great. Thanks!

But locale support for UTF-8 is not included in try-reflex. This is the first time I have been in contact with Nix and I have not been able to understand how to modify the environment to support UTF-8.

I could not build reflex-todomvc because of this.

What should I do to use UTF-8?

Hi Pär-Anders,

Could you give me some more information about your situation? It would be helpful to know your OS, the locale your machine is in usually, and the error message (and any other output) you're getting.

Thanks, Ryan

Hi Ryan,

Thanks for helping!

I'm on Ubuntu 14.04

pa@pacompute:~$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
POSIX
sv_SE.utf8

LC_*==sv_SE.UTF-8

Now when using Nix

[nix-shell:~/tmp/try-reflex/try-reflex]$ locale -a
C
POSIX

LC_*==

When running examples/host.hs and entering 'abcdeå':

When building reflex-todomvc using ghcjs:

[nix-shell:~/tmp/try-reflex/try-reflex/reflex-todomvc]$ cabal install --ghcjs

Hi Pär-Anders,

I've made a change that should allow your default locale to be used inside the nix-shell. I think this will resolve your issue - please let me know if it doesn't!

Thanks Ryan!

Works like a charm!
