Wildcard expressions and unicode ???

[Richmond Mathewson]

  I suppose it was inevitable . . .  :)

As I wrote yesterday, I found out how to search for and replace unicode 
characters
in a field:

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

which is jolly good, as far as it goes . . .

However; suppose I wish to search for all instances of numToChar(57888) 
in front of another unicode character
and move them so that they are behind that unicode character . . .

Let us imagine this sort of script: (where  ?  represents any, i.e. 
wildcard, unicode character)

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

interestingly enough; on compiling in RunRev 4 it says that script is OK 
(mind you it says that
about lots of script that, on attempting to run, throw a "bluey"),

Well, Ha, Ha; it is OK insofar as it does nothing!
