Is %replace and %enc supported in log4j 1.2.x?. Relevant configurations were found in log4j 2.x documentation [1] but not for older versions.

No.
Features found in log4j 2 may not be found in log4j 1. According to their site:
The API for Log4j 2 is not compatible with Log4j 1.x, however an adapter is available to allow applications to continue to use the Log4j 1.x API.
