If you set the REMOVE_CONTROL_CHARACTERS parameter to ON in the ICUCNVPROPERTY
statement, control characters for the source code page are removed during code page conversions.
For example, to remove control characters in conversions from code page
ibm-37_P100-1995, use the following syntax:
ICUCNVPROPERTY=(189,REMOVE_CONTROL_CHARACTERS,ON)
To avoid having to remove control characters in conversions, do not store control
characters in legacy data.
