Basically, the idea is to define the good characters, and use
STRTRAN on the original string to remove the good characters. That
leaves all the bad characters, right? Now run STRTRAN against the
original string with the bad chars; all that will be left is the good
chars. In code:
LPARAMETERS targetStr
* We want only chars < 128
good = ""
FOR ii = 1 TO 127
good = good + CHR(ii)
ENDFOR
bad = STRTRAN(targetStr, good)
IF EMPTY(bad)
ret = targetStr
ELSE
ret = STRTRAN(targetStr, bad)
ENDIF
RETURN ret
