fix: Encode Chinese characters with Unicode before querying to match the Unicode encoded Chinese characters in the db

[xhdd123321]

Summary

The Chinese characters in the inputs and outputs of the workflow table are stored in Unicode encoding, which prevents the search box from querying workflow run log in Chinese.I encoded the Chinese characters with Unicode before searching the table, so that a match can be hit normally.I have tested that this change will not affect language queries that are not encoded in Unicode.

Resolve #12039 I noticed that someone had mentioned this error before, but it was closed.
