On what kind of system?

Agda will "crash" if you try to print a character which is not supported
by the underlying locale:

  $ LC_CTYPE=sv_SE.utf8 ghc -e 'putStrLn "\x2200"'
  ∀
  $ LC_CTYPE=sv_SE.iso88591 ghc -e 'putStrLn "\x2200"'
  <interactive>: <stdout>: hPutChar: invalid argument (Invalid or incomplete multibyte or wide character)

One option:

• M-x customize-group RET haskell-ghci RET
• Add three new arguments to "Haskell Ghci Program Args": +RTS -MxxG
  -RTS

You could also use the GHCRTS environment variable.

Yes.
