Subject: [PATCH] Fix: string merge bug about agent TextProcessing. (\m)
 (#10211)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### What problem does this PR solve?
An error occurred while merging strings containing '\m' in the Text
Processing function of the agent.

Convert \ m to m using regular expressions

From my example alone, it doesn't affect the original meaning, it's
still math
