2311800 - ASE raises error 1579 severity 16 when functions such as UPPER() and LOWER() encounter an invalid byte sequence in utf8 data

Prior to 15.7 ESD#2, statements such as "select upper(c1) from t1" (where c1 is a column containing utf8 data that includes at least one row with a bad value) would raise error 2431 with severity 10, return a NULL for the bad value, and complete processing the result set.  In ESD#2 and higher, ASE now raises error 1579 with severity 16 instead of 2431 with severity 10, causing the statement to be aborted.
