Denis,

Untested idea: 

1. Fill a dict with pre-calculated repr() values for chars you want to
replace (replaceDict)

2. Create a set() of chars that you want to replace (replaceSet).

3. Replace if (n < 32) ... test with if char in replaceSet

4. Lookup the replacement via replaceDict[ char ] vs. calculating via
repr()

5. Have result = list(), then replace result += char with result.append(
char )

6. Return ''.join( result )

Does this help?
