Comment (by nh2):

 On Windows Server 2016 (as provisioned by AWS Windows instances, into
 which I RDP'd), with the Locale set to Japanese (as described in
 https://www.java.com/en/download/help/locale.xml -- this sets the code
 page, as shown by `chcp`, to `932` in PowerShell and cmd.exe), when trying
 to reproduce the bug with the code from the issue description, **I already
 see GHC itself dying with the same error** during `stack setup`:

 {{{

 (Note that this is not how I see it in PowerShell, where all backslashes
 are replaced by the Yen sign, but this is as I see it when I copy-paste
 the output into Sublime Text 3 or a Firefox window).
