I think you can remove all chars below x’40’ because these are generally not printable, or used as display attributes.

The rest should work IMHO.

I'm preloading an old-school 5250 display file with data coming in from a
Windows app. Is there a good way to remove unprintable chars? The RPG
code is throwing a RNQ1251 (Permanent I/O error occurred in file &1). I
need to cleanse the data to prevent this.

FWIW, the current char is x'12', which is DC2 per the code page 37 chart.
