fix(subtitles): implement comprehensive Chinese character loss detect…#229
Conversation
…ion and fallback for ASS subtitle parsing - Add intelligent character loss detection to identify when subsrt library drops Chinese characters - Implement custom ASS parser as fallback mechanism for problematic subtitle files - Add comprehensive test suite covering 51 edge cases and boundary conditions - Fix ASS tag stripping order to prioritize newline processing before style removal - Enhance bilingual subtitle separation with improved script detection - Add detailed logging for debugging subtitle parsing issues Changes: - parseWithSubsrt: Add hasChineseCharacterLoss detection and parseCustomAss fallback - Add parseCustomAss: Complete ASS format parser with proper Dialogue handling - Add parseAssDialogue: Parse ASS Dialogue lines with accurate time parsing - Add hasChineseCharacterLoss: Detect Chinese character loss by comparing original vs parsed content - Update stripAssTags: Process newlines before style tags to prevent character truncation - Add SubtitleReader.comprehensive.test.ts: 51 comprehensive tests covering all scenarios - Update SubtitleReader.test.ts: Add regression test for \N newline character loss This fix resolves the critical issue where subsrt library was dropping the first Chinese character (《老友记》 → 老友记) in ASS subtitles and ensures robust parsing of various subtitle formats including edge cases with complex styling and bilingual content. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Estimated code review effort🎯 3 (Moderate) | ⏱️ ~20 分钟 理由： 变更涉及多个新函数的引入（自定义 ASS 解析器、中文字符检测），需要理解 ASS 格式解析逻辑和回退机制的正确性。同时包含大量新测试代码，但测试内容相对独立。变更范围中等，逻辑密度中等。 Possibly related PRs

189-221: 自定义 ASS 解析器实现正确实现逻辑清晰：正确识别
[Events]section，解析Dialogue:行，并处理 section 边界。防御性编程良好（Line 214 的 null 检查）。
223-249: Dialogue 行解析实现正确正确处理了 ASS Dialogue 格式的复杂性：
- 去除
Dialogue:前缀- 正确分割前 9 个字段
- 合并剩余部分作为文本（处理文本中包含逗号的情况）
- 时间转换为毫秒精度
- 良好的错误处理
251-266: ASS 时间解析实现正确正则表达式和时间计算逻辑正确：
- 匹配
H:MM:SS.CC格式（centiseconds = 百分之一秒）- 正确转换为秒（Line 259-263）
- 对无效格式返回 NaN
600-608: ASS 标签清理顺序修复正确关键修复：在移除样式标签之前先处理换行符（Line 602-604）。这防止了
\N被错误地当作样式标签的一部分处理，解决了 PR 中描述的中文字符丢失问题。处理顺序：
\N→ 换行符\n→ 换行符\h→ 空格- 移除
{...}样式块- 清理残留标记
146-166: 检测到中文字符丢失的逻辑结构清晰，但需修复 Line 283 的 bugfallback 机制设计合理：首先尝试 subsrt 解析，然后检测中文字符丢失，最后在必要时切换到自定义 ASS 解析器。然而，Line 283 存在一个关键 bug。
应用此 diff 修复 Line 283 的 bug：
const parsedChinese = subsrtCues .map((cue: any) => String(cue.text || '')) .join('') - .match(/[\u4e00-\u9fff]+/g) || [].join('') + .match(/[\u4e00-\u9fff]+/g) || [] + const parsedChineseStr = parsedChinese.join('')然后在 Line 288 使用
parsedChineseStr.length替代parsedChinese.length。当前代码在 Line 283 尝试对数组字面量
[]调用.join('')，这会导致语法错误或逻辑错误。Likely an incorrect or invalid review comment.
src/renderer/src/services/subtitles/__tests__/SubtitleReader.test.ts (1)
25-45: 回归测试设计良好，准确验证了修复测试用例精确覆盖了 PR 描述的问题场景：
- 包含中文字符
- 包含
\N换行符- 包含 ASS 样式标记
- 验证中文字符不丢失
- 验证样式标记被正确清除
- 验证
\N转换为真实换行符

🧹 Nitpick | 🔵 Trivial
综合测试套件覆盖全面，质量优秀
测试套件包含 51 个测试用例，覆盖范围广泛：
- 基础功能和格式检测
- JSON/SRT/VTT/ASS 解析
- 双语字幕分离
- ASS 标签清理
- 时间解析
- 脚本检测
- 错误处理和边界情况
- 性能测试
测试组织清晰，使用合适的 mock，正确验证预期行为。
可选建议：Line 695 的性能测试阈值设置为 5 秒。考虑根据 CI 环境调整此值，或将其设为可配置参数，以适应不同的运行环境。
- expect(endTime - startTime).toBeLessThan(5000) // 应该在5秒内完成
+ const PERF_THRESHOLD = process.env.CI ? 10000 : 5000 // CI环境允许更长时间
+ expect(endTime - startTime).toBeLessThan(PERF_THRESHOLD)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In
src/renderer/src/services/subtitles/__tests__/SubtitleReader.comprehensive.test.ts
lines 1-820, the performance test at line ~695 hardcodes a 5000ms threshold
which may be flaky in CI; change the test to use a configurable timeout (read
from an env var like SUBTITLE_TEST_MAX_MS with a sensible default, e.g., 5000)
or relax the assertion to be environment-tolerant (e.g., assert result.length
and log duration instead of failing, or use a higher/default threshold) and
update the test to fall back to the default when the env var is not set.

Changes:
This fix resolves the critical issue where subsrt library was dropping the first Chinese character (《老友记》 → 老友记) in ASS subtitles and ensures robust parsing of various subtitle formats including edge cases with complex styling and bilingual content.
