Title: fix exception page when template contains utf-8 and parameters contain utf-8

There is `Error during failsafe response: incompatible character encodings: ASCII-8BIT and UTF-8` when:

- template contains utf-8 symbols near place where exception raised
- request with post method with utf-8 parameters
