Unicode is not prettyprinted correctly

[DanBurton]

See, for example: 94a3bcd

UnicodeIdents.hs

猫 = ()

UnicodeIdents.hs.prettyprinter.golden

+ = ()

This golden file is known to be incorrect.

Looks like the unicode character gets truncated to 8 bits: ord '猫' is 0x732b, ord '+' is 0x2b.

Easy to do:

import qualified Data.ByteString.Char8 as BS
BS.pack "猫" -- => "+"

But I'm not sure why or where it's happening here.
