`set langmap` with non ascii characters causes vdebug to exit with: Error starting Vdebug: <class 'UnicodeDecodeError'>

[nexusstar]

I am using Neovim v0.2.2 on Windows 10 (WLS Kali installed) running on command prompt
OS
Linux Q306 4.4.0-43-Microsoft #1-Microsoft Wed Dec 31 14:42:53 PST 2014 x86_64 GNU/Linux

vdebug
master -> 5e1d263

In my configuration files I've got:

set langmap=ч`,яq,вw,еe,рr,тt,ъy,уu,иi,оo,пp,ш[,щ],аa,сs,дd,фf,гg,хh,йj,кk,лl,;;,'',ю\\,зz,ьx,цc,жv,бb,нn,мm,Ч~,ЯQ,ВW,ЕE,РR,ТT,ЪY,УU,ИI,ОO,ПP,Ш{,Щ},АA,СS,ДD,ФF,ГG,ХH,ЙJ,КK,ЛL,::,"",Ю|,ЗZ,ѝX,ЦC,ЖV,БB,НN,МM,„<,“>

which causes following error when all configuration and plugins are enabled:

debug will wait for a connection in the background
Found connection, starting debugger
Error starting Vdebug: <class 'UnicodeDecodeError'>

If I leave only this one I receive following errors:

Found connection, starting debugger

I check with the same configuration in Ubuntu 16.04 and there is no problem.

@nexusstar So is this reproducable on ubuntu? or is this specific to the linux subsystem on windows?

[BlackIkeEagle]

@nexusstar ok I can reproduce this. I'm trying to figure out how to solve this

@BlackIkeEagle sorry for the late replay and yes I manage to reproduce it on Ubuntu.

@nexusstar no worries, I can reproduce it and am trying to find a solution. The solution is not as trivial as first thought :(
