hi, are there any Japanese Haskell users with Windows around that could try
import GHC.IO.Encoding
getForeignEncoding

for me and tell me what it outputs? I'm trying to fix a bug in Haskell's rocksdb bindings
igrep
2018-04-02 07:39:31 +0900
From my console:

λ stack exec ghci
GHCi, version 8.2.2:   :? for help
Loaded GHCi configuration from C:\Users\igrep\Dropbox\dot-files\dot-files\.ghci
[Prelude]
> import GHC.IO.Encoding
[Prelude GHC.IO.Encoding]
> getForeignEncoding
CP932

@igrep Thanks a lot. How did you get this setting? Is it what happens when you install a Japanese Windows edition (and which version?), or after changing it from an English install? I'm trying to set my system so I also get CP932
りんご姫
2018-04-03 23:59:49 +0900
What it outputs, is really depending on the code page which the command prompt (or powershell) uses, by default Windows Japanese edition set it to CP932. If you get other than this, you need to change it to CP932 by calling chcp 932 before running haskell or (I believe) you can use Japanese edition.
nh2
2018-04-04 02:46:01 +0900
Yes, that makes sense. I'm just asking because I want to test my changes on as realistic a Japanese system as I can get (to reproduce the bug found by users reported to run on Japanese Windows), and I'm not sure if just the chcp 932 is enough.
nh2
2018-04-04 02:46:22 +0900
The setting sets set this default seems to be https://knowledgebase.progress.com/articles/Article/4677:

2018-04-04 02:46:51 +0900
Open Windows Control Panel
Select Region and Language
Click on the Administrative tab
Under Language for non-Unicode programs, click on Change System Locale
nh2
2018-04-04 02:49:04 +0900
I set this to Japanese (Japan) and after a reboot I got CP932 in the ghci
りんご姫
2018-04-04 05:04:18 +0900
If the bug (maybe) rely on the result of getForeignEncoding then, I think chcp 932 is just enough, since if we put chcp 65001 and then run getForeignEncoding, it outputs UTF-8, as we intended the result to be.
igrep
2018-04-04 07:58:18 +0900
I agree with りんご姫. If the error is related to character encoding, chcp 65001 or chcp 20127 is usually a sufficient workaround.
igrep
2018-04-04 08:01:39 +0900
If your error is similar to one referred in https://haskell.jp/blog/posts/2017/windows-gotchas.html, codes in the article would help you.

@igrep @りんご姫 thanks a lot!
Also your linked article seems to be very relevant to me right now.
Can you tell me, does ghc itself usually work when working under the Japenese locale?
For me, when I run stack exec -- ghc --version with the locale set to Japanese, I get
C:\Users\
ghc-pkg.EXE: <stdout>: commitBuffer: invalid argument (invalid character)

Is that the same for you?
igrep
2018-04-10 08:01:24 +0900
GHC should work under the Japanese locale usually...
> stack exec ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 8.2.2

Hmmm... You might have got a bug of GHC...?:confused:
nh2
2018-04-10 08:03:55 +0900
@igrep I'm also not sure what's going on, I just installed it with the stack installer https://www.stackage.org/stack/windows-x86_64-installer
nh2
2018-04-10 08:05:02 +0900
@igrep just to double check, for me it fails when I have both the Japanese locale and a Japanese user name, do you think this combination should work?
nh2
2018-04-10 08:05:21 +0900
because that funny newline split is exactly where the user name should be
igrep
2018-04-10 08:06:46 +0900
@nh2 Oh, yeah, it can be related.
Because GHC installed via stack is usually installed under %LOCALAPPDATA%.
E.g.
> stack exec which ghc
/c/Users/Yuji/AppData/Local/Programs/stack/x86_64-windows/ghc-8.2.2/bin/ghc
igrep
2018-04-10 08:08:03 +0900
We know we should avoid making %USERPROFILE% contain Japanese name, which causes some errors.
nh2
2018-04-10 08:24:51 +0900
@igrep Is that also written down / documented somewhere? I would like to know more about it, maybe I can even fix it
igrep
2018-04-10 08:26:30 +0900
Hmmm... Sorry, I don't know the detail. Maybe we're too accustomed to avoid Japanese characters before fixing it... :disappointed_relieved:
