Problem Note 64428: The KCVT() function performs poorly in SAS® 9.4M4 (TS1M4) and later releases
 |  |  |  |  |
Beginning in SAS 9.4M4, the KCVT() function performs poorly. You encounter this issue when you use the function in a SAS session that runs with option ENCODING=UTF-8.
For example, the problem occurs when you submit a call to KCVT() similar to the following:
str = kcvt(str, 'latin1', 'utf8');
