- 符号混输不再挡读得成拼音的编码：混输本来就只认整串精确匹配，xi → ξ 也照样混入；单字母编码仍不混。 - 构建器读取 msime-dictionary 新增的 custom/symbols.txt（拼音<TAB>符号），把 dian → · 、、 shuminghao → 《》 〈〉 等标点读音写进 symbol_code，书名号、引号、括号成对给出。 - emoji 混输改用新的 query_mixed_emoji，只认整串精确等于关键词，不再按前缀带出 emoji；双拼下只查 展开后的全拼，并和符号一样只在光标位于末尾时查询。Shift+E 的 emoji 模式仍按前缀查。 - 同步更新设置页说明、出厂与开发配置注释和 README。
