- 为 resolve 添加带 range 参数的重载 - resolve(string c) 只计算一次 get_unicode_range，然后传给循环中的 resolve - 每个字符减少多次 UTF-8 解码开销 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 在 unicode.cpp 中添加 unicode_range_cache 缓存 string->string 映射 - 添加 get_utf8_code_cached 缓存 string->int 映射 - 将 smart_font.cpp 中的 get_utf8_code 委托给缓存版本 - 大幅减少 strict_cork_to_utf8 和 decode_from_utf8 的重复调用 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 缓存 dpi_str 和 sz_str 到局部变量 - 避免在 t1/t2/t3/panic 构造中重复调用 as_string Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 缓存 vdpi_str 和 hdpi_str 避免重复 as_string - 移除 smart_font/math_smart_font/prog_smart_font 中多余的 normalize_half_multiple_size 调用（smart_font_bis 已做） Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 将 string r= s 改为 string r 避免每次复制整个字符串 - advance 内部会给 r 重新赋值，初始拷贝是浪费的 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 缓存 dpi_str 和 attempt_str 到局部变量 - 避免在 extra 构造中重复调用 as_string Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 在 resolve(string c) 中提前计算 sf 并复用 - 减少 math letter 替换的重复哈希查找 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 提前计算 is_rubber、starts(c, \"<wide-\")、fn[SUBFONT_MAIN]->supports(c) - 避免在 family_tokens 内层循环中重复执行相同检查 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 在 resolve(c, range, fam, attempt) 中先检查 fam 是否包含 '=' - 对于不含 '=' 的 fam（大多数情况）跳过 tokenize 开销 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
移除验证优化效果时添加的临时调试输出，保持代码整洁。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

- test_resolve_performance → test_resolve_mixed_chars（该测试验证正确性而非性能） - 移除 find_font.cpp 和 font_translate.cpp 中解释显而易见代码的注释 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

get_unicode_range(c)提取到循环外，只计算一次sz_str和dpi_strvdpi_str/hdpi_str，移除多余normalizeget_extents/get_xpositions/draw_fixed中string r= s改为string rdpi_str和attempt_stris_rubber/starts(c, "<wide-")移出循环=的 fam 执行无意义trimmed_tokenize测试
