[ERROR] Locale Monetary Symbol Prints Wrongly on Windows : Cygwin

Hi Corinna,

I can't update to 3.5+, I tried reinstalling using the Cygwin setup

Using "uname -a", my current version is 3.4.6-1.x86_64.

I assume 3.5 hasn't been released officially.

May I know where to get the test release?

In the terminal, when I use $LC_MONETARY = "en_ZM.utf-8" locale -ck 

Cygwin replies "-bash: LC_MONETARY: command not found"

Thank you very much.

Kind Regards,

YEO Kai Wei
