ide crashes without notice if unprivileged user has cyrillic username on windows 8

[mugiseyebrows]

I have Пользователь user account on windows 8 and arduino installer created directory C:\Users\Џ®«м§®ў вҐ«м with (AppData and Documents directories inside) which is obviously character encoding issue. When ide starts without elevated permissions it crashes without notice on "preparing boards" stage. It works if "run as administrator" used though. I run arduino_debug.exe and it shows "access denied" (отказано в доступе) error:

And it gives me a clue: Пользователь user account has no write permissions for Џ®«м§®ў ⥫м. icacls "C:\Users\?R<м§Rў в?<м" /grant Пользователь:(OI)(CI)F (with administrator rights of course) solves this issue (I didnt type in ?R<м§Rў в?<м, i tabbed it, dont know why its different this time).
I encounter this issue on two machines with win8 so I guess its not just me.
Windows 8.1 x64, arduino 1.6.5 installed with installer, (I have jre 1.8.0_60 x64, jdk 1.8.0_60 x64 on this machine if that maters (I assume arduino uses its own java env))

@mugiseyebrows I'm finding a hard time at trying to reproduce the issue. Is your windows in Russian?

[mugiseyebrows]

@ffissore Oh, sorry, I forgot to mention that. Yes, its in Russian.

I guess it's actually nsis issue. Is installation script in repository? I can't find it.

No, it does have to do with the installer. Apparently, Windows Registry is storing your username using a charset the IDE can't convert to UTF8, which is strange, since the native API is using wchar_t which is the correct type in this case (AFAIK). This one will take a while to solve and help from some windows expert is needed. In the meanwhile, create a portable folder in the IDE folder (something like c:\program files\Arduino\portable). The IDE will store everything but the sketchbook under portable: this will work around your problem BUT it will also mean that, next time you install the IDE, you will lose your settings, unless you back them up

Seems like duplicate of #3360
CP866 -> CP1251 'Пользователь' -> 'Џ®«м§®ў вҐ«м'
Batch files on russian windows talks in CP866 by default, and other things talks in CP1251, which leads to confusions all the time.

#3360 was fixed by fetching data directly from the windows registry, instead of executing regedit from the command line.
