tju-yxq opened a new pull request, #1425:
URL: https://github.com/apache/rocketmq-dashboard/pull/1425

   ## What is the purpose of the change
   
   Fixes #1424
   
   When truncating a message body larger than 64 KB for display, the truncation 
point could fall in the middle of a multi-byte UTF-8 character (CJK, emoji, 
etc.). The decoder with `CodingErrorAction.REPORT` would throw 
`CharacterCodingException`, and the body would be displayed as BASE64 instead 
of readable text.
   
   ## Brief changelog
   
   - **`RocketMQMessageProvider.java`**: Added UTF-8 character boundary 
adjustment before decoding. When truncation is needed, walk back from the 
truncation point past any continuation bytes (`10xxxxxx`) and the leading byte 
(`11xxxxxx`) to land on a complete character boundary.
   
   ## Verifying this change
   
   1. Produce a message with >64KB UTF-8 text containing multi-byte characters 
near the 64KB boundary.
   2. Query the message in Studio.
   3. Before fix: body shows as BASE64.
   4. After fix: body shows as readable UTF-8 text with truncation indicator.
