Jason Dere commented on HIVE-13063:
-----------------------------------

[~afernandez], looks like the golden files for show_functions.q/udf_chr.q may 
need to be updated.

> Create UDFs for CHR and REPLACE

> Create UDFS for these functions.
> CHR: convert n where n : [0, 256) into the ascii equivalent as a varchar. If 
> n is less than 0 or greater than 255, return the empty string. If n is 0, 
> return null.
> REPLACE: replace all substrings of 'str' that match 'search' with 'rep'.
> Example. SELECT REPLACE('Hack and Hue', 'H', 'BL');
> Equals 'BLack and BLue'"
