 # 204_1 CJK标点符号间距调整功能实现
 
-## 2025/01/17
+## 如何测试
+添加了测试文件`TeXmacs/tests/tmu/204_1.tmu`，包含以下测试场景：
+- 行首和行尾夹注符号的0.5字宽调整
+- 普通符号后跟左夹注符号的1.5字宽调整
+- 夹注符号后跟普通符号的1.5字宽调整
+- 连续符号的混合字宽调整（前两个1字宽，后续1.5字宽）
+
+关于双引号重叠问题的测试：
+- 将字体设置为 kaiti SC，中文输入法输入双引号，看是否会重叠
+
+## 2025/12/15 修复双引号重叠问题
+### What
+- 因为一些cjk字体本身没有设置字距，`text_box_rep::right_contract_kerning `和`text_box_rep::left_contract_kerning`会导致额外的压缩，最终导致了重叠问题
+- 额外删去了`add_upright_left_protrusion`和`add_upright_right_protrusion`里的关于中文单双引号凸出设置，因为西方字体凸出函数不应该处理这些
+
+### How
+进行额外判定，如果没有字距或者压缩完小于0时，不压缩
+
+## 2025/11/16
 
 ### Why
 在TeXmacs中处理中日韩（CJK）文本时，标点符号的间距调整是一个重要的排版需求。特别是对于夹注符号（如括号）和普通标点符号之间的间距，需要根据不同的上下文进行智能调整，以符合中文排版的规范和美观要求。现有的自动间距功能无法满足这种精细的标点符号间距控制需求。https://www.w3.org/TR/clreq/#punctuation_width_adjustment 参考 6.3.2 标点符号的宽度调整

 2. **段落处理增强**：增强了lazy_paragraph的处理能力，增加了新的数据结构和算法
 3. **文本框功能增强**：为text_box添加了kerning收缩功能
 
-#### 测试验证
-添加了测试文件`TeXmacs/tests/tmu/204_1.tmu`，包含以下测试场景：
-- 行首和行尾夹注符号的0.5字宽调整
-- 普通符号后跟左夹注符号的1.5字宽调整
-- 夹注符号后跟普通符号的1.5字宽调整
-- 连续符号的混合字宽调整（前两个1字宽，后续1.5字宽）
-
 #### 兼容性考虑
 1. **向后兼容**：新添加的虚函数在基类中提供默认实现，不影响现有代码
 2. **性能影响**：新增的标点符号识别和调整逻辑仅在CJK语言环境下启用
