Brandon Williams commented on CASSANDRA-17617:
----------------------------------------------
We don't have any for timing, and I don't think this is the juncture to add
one. Since functionality didn't change and this is a trivial patch I think a
clean CI run is enough. To that end...

> CQLSH unicode control character list is too liberal
> ---------------------------------------------------
>
> Key: CASSANDRA-17617
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17617
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Interpreter
> Reporter: Tanuj Nayak
> Assignee: Tanuj Nayak
> Priority: Normal
> Fix For: 3.11.x, 4.0.x, 4.1.x
>
>
> It appears that the list of escaped unicode control characters
> [here|https://github.com/apache/cassandra/blob/53a67ff2c36d90d337aba1409498de29931d4279/pylib/cqlshlib/formatting.py#L32]
> is a bit too liberal. It seems to include characters such as '1' (0x31) and
> '0' (0x30) which do not need to be escaped. It seems that the actual range
> should be 0x00 - 0x1F and 0x7F+ as corroborated [by this
> page|https://en.wikipedia.org/wiki/Unicode_control_characters].
>
> This causes unnecessary escaping and regex substitutions on the CQLSH end
> whenever common characters such as any punctuation or a 0 or a 1 appear in
> the text column of a table. One might notice that a table with a text column
> filled with 2's will take much less time to print than one with all 0's for
> this reason.
