+
+### 3.1 确定性测试（单元测试）
+```bash
+xmake b converter_test && xmake r converter_test
+```
+
+### 3.2 非确定性测试（文档验证）
+进入插件会话，新建Python、Julia或Goldfish会话，输入中文，不会出现乱码（验证本次协议迁移不会带来字体解析问题）
+
+### 3.3 基准测试（量化优化效率）
+```python
+import re
+import time

+
+## 4 What
+- 更改插件系统（Python、Julia、Goldfish、Autosave、Quiver、TikZ）的字符编码协议为 **UTF-8**
+- 保持 Mogan 编辑器内部“母语”仍为 **Cork** 编码以保证渲染与排版树稳定
+
+## 5 Why
+旧版使用 `SourceCode`（Cork转义ASCII）传输数据，内存带宽高且效率低下
+
+## 6 How
+1. 修正 `verbatim.cpp` 的 `encode` 映射，统一输入输出端 `"auto"` 行为。在输入端通过 `get_locale_charset ()` 降级为 `"UTF-8"` 匹配 `utf8_to_cork`
+2. 更替 6 个插件 init 配置，将序列化编码由 `"SourceCode"` 变更为 `"utf-8"`
+3. 将 `MoganJulia.jl` 的自动补全格式从 `"scheme:"` 通道更替为具有 Scheme 树级 UTF-8 还原能力的 `"scheme_u8:"` 接口
