Fwd: Mucking around with unicodeText fields ???

This WORKS:

on mouseUp
    set the useUnicode to true
    if the unicodeText of fld "FIRST" contains (numToChar(57888) & 
numToChar(57999)) then
       get the unicodeText of fld "FIRST"
       replace (numToChar(57888) & numToChar(57999)) with 
(numToChar(57999) & numToChar(57888)) in it
       set the unicodeText of fld "FIRST" to it
    end if
end mouseUp
