Improper error message on hamlet file having BOTH Tab and Unicode (non-ascii) chars about shakespeare

[snoyberg]

That error message is coming from GHC, not Hamlet. GHC is not able to print out the non-ASCII character. This is a known issue with Windows. I believe. By contrast, here's the output I get on my Linux box:

tabs.hs:4:10:
    Exception when trying to run compile-time code:
      "<table>
    <tr>
        <td>some text</td>

<ul>
 <li>K.Deniz Yılmaz
 <li>some other text
" (line 2, column 9):
Tabs are not allowed in Hamlet indentation
      Code: hamletFile "tabs.hamlet"
    In the expression: $(hamletFile "tabs.hamlet")
    In an equation for `main': main = $(hamletFile "tabs.hamlet")

from the POV of user it's not important. receiving such messages, i modified all my templates with tabs to not contain non-ascii chars, then spent time for discovering and reporting a bug

i know that it cannot be fixed in ghc (except for changing console code page), so it can be masked off in application either by catching an excpetion or checking OS before printing to the console

in the worst case, it may be added to FAQ so users don't spend time like me

The wiki is a good place to mention this. If you could do so, it would be appreciated. I'm not familiar enough with Windows to know how to detect if printing will fail. On my Windows system at least, the messages seem to print properly as well.
