**Issue Evaluation** Category: `bug` | Status: **Confirmed** Verified against `server/src/main/java/org/apache/rocketmq/studio/provider/apache/RocketMQMessageProvider.java`: - `abbreviate()` (line ~775) uses `value.substring(0, maxLength)` — operates on UTF-16 `char` indices, not code points. - `MAX_PROPERTY_VALUE_CHARS = 1024` (line 86). - `hasOversizedProperty()` (line ~768) uses `value.length() > MAX_PROPERTY_VALUE_CHARS` — also UTF-16 length, not code point count. **Note:** The file path in the issue (`MessagePropertyDisplay.java`) does not exist; the actual code lives in `RocketMQMessageProvider.java` (methods `abbreviate`, `limitProperties`, `hasOversizedProperty`). **Root Cause:** `String.substring` and `String.length()` split surrogate pairs for supplementary characters (emoji, CJK Extension-B, etc.). **Severity:** low-medium — cosmetic data corruption in truncated display values. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
