Well, it depends on what your definition of "efficient" is. If you want a
1-liner:
put replaceText(tSource, "[^A-Za-z0-9\-]+", empty) into tDest
That's using regular expression. But that might be a lot less performance
(speed-wise) than doing it yourself in a loop:
repeat for each char c in tSource
if c is in "abcdef...WXYZ0123456789-" then
put c after tDest
end if
end repeat
