[Richard Suchenwirth] 2006-04-05 - If you want to know the difference between two (one-byte) [encoding]s, the following codelet may help:

 proc encodiff {e1 e2} {
   set res ""
   for {set i 32} {$i<256} {incr i} {
      set c [format %c $i]
      if {[encoding convertfrom $e1 $c] ne [encoding convertfrom $e2 $c]} {
         append res [format %02X $i] \
              [encoding convertfrom $e1 $c] | [encoding convertfrom $e2 $c]\n
      } 
   }
   set res
 }
#-- Testing demo:
 % encodiff iso8859-1 cp1252

Obviously, [Windows]' cp1252 filled most of the "high control" positions with extra characters, but is otherwise identical to iso8859-1.
