I don't think so. For me, this is a fine implementation of chr():
Maybe a check should be added to make sure 'i' is between 0 and 255 :-)
But the resposibility to construct string objects is not chr()'s
In a CPython extension and probably also in the core there are helper
functions to build these strings, the implementor of chr() would use them.
