You can just continue to use the same control codes, that is 001F instead
of 1F. This part of the UNICODE character set is not regulated by ISO/IEC
10 646 but is rather by ISO/IEC 6420 - Control codes, as before.

This seems a little messy but is done intentionally. I can remember control
codes as a subject in at least one JTC 1/SC2 meeting....

Some relevant control codes:

Field Separator : dec 28 hex 001C
Group Separator : dec 29 hex 001D
Record Separator: dec 30 hex 001E
Unit Separator : dec 31 hex 001F
