+# 重构is_emoji_character函数
+
+## 2025/08/01
+
+### 如何测试
+
+本次提交修改了lolly，所以需要执行
+
+```bash
+xmake require --force lolly
+```
+
+强制更新这个包
+
+随后在206_5.tmu便可以不指定字体显示emoji（文件已经设置好assign）
+
+### What
+
+修改is_emoji_character和lolly中的unicode_get_range函数，为以后字体选择做准备
+
+### How
+
+修改了unicode.cpp(lolly)和unicode.cpp中的is_emoji_character函数
+
+### Why
+
+为以后字体选择做准备
