Hi folks, my name is Juan Maiz and i&#39;m starting to study Haskell (again).  Is anyone from Brazil in the list?i<br><br>I&#39;m currently reading The Haskell Road to Logic, Maths and Programming and having a lot of (geek) fun. By the way, i found this: <a href="http://www.mail-archive.com/haskell-cafe@haskell.org/msg45406.html">http://www.mail-archive.com/haskell-cafe@haskell.org/msg45406.html</a> . It was sent by 
<span class="sender">Mattias Bengtsson. I made something similar using Ruby&#39;s Treetop, with the difference that my concern was to</span> validate and generate truth tables for formulas using Unicode.<br><br>So... my first noob question to the list: What is the difference of Unicode support in HUGS and GHCI ? In GHCI I can do something like:<br>
<br><br>(∧) = (&amp;&amp;)<br>Prelude&gt; True ∧ False  <br><i>False</i><br><br>(The carachter is the unicode for conjunction U+2227)<br><br>But in HUGS i can&#39;t. It says:<br><br>ERROR &quot;conjunction.hs&quot;:1 - Unrecognised character `\8743&#39;<br>
<br>Somebody?<br><br><br><div class="gmail_quote">On Mon, Nov 23, 2009 at 1:26 PM, Eric Kow <span dir="ltr">&lt;<a href="mailto:eric.kow@gmail.com">eric.kow@gmail.com</a>&gt;</span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Minor aside.<br>

&gt; -&gt; Could be the first GUI to build on hackage :)<br>
<br>
If you have wxWidgets installed, the new fully Cabalised wxHaskell<br>
builds just fine.  It&#39;s quite handy/refreshing for &#39;cabal install wx&#39; to<br>
finally &quot;just work&quot; :-)<br>
<br>
Unless you mean &quot;build on the Hackage server&quot; which should also be<br>
possible in principle, although the wxHaskell folks may want to have<br>
a quick look at<br>
