Comment (by Henk-Jan):

 When I remove the BOM by saving the file in ANSI coding (using Notepad), I
 get the following message from GHC:

     Camels.hs:152:56:
         lexical error in string/character literal (UTF-8 decoding error)

 This is because of an o-umlaut in the comments.
 The file can be found at:
 https://raw.githubusercontent.com/wxHaskell/wxHaskell/master/samples/contrib/Camels.hs

 (Geany states that the file is in CP1252 code and displays it correctly)
