[mapserver-dev] getExpressionString issue

[Jeff McKenna]

Hi David,

I just realized that I did recently face an odd issue on Ubuntu as well: 
I was generating a mapfile with mapscript, and everything was fine on 
Windows.  But on the client's Ubuntu server the same process was having 
problems - such as values being displayed.  This was difficult to debug. 
  The fix?  Oh boy, yikes.  Recent versions of MapServer require 
mapfiles to be in UTF-8 format.  I tested that on Ubuntu through iconv 
tools and bingo, that was indeed the problem.

If it isn't related to your case, then at least this is a good one to 
keep in mind.  It sure humbled me :)

Happy Easter to all.
