Description

When creating jobhistory file, job name is trimmed within 50 characters by default, and the name is URL-encoded after the job name is trimmed. Therefore, if there are some multibyte characters in the job name, the encoded job name can be longer than 50 characters. Eventually it can break the limit of the file name (Usually 255 characters).
