Translation language not recognized, incorrectly forced to Pinyin

[linhtran156]

Describe the bug
The lyric parser's language auto-detection mechanism seems to completely override explicitly defined language metadata and tags across multiple formats (.eslrc, .lrc, and .ttml).
Even when I manually inject strict language attributes, the application incorrectly detects the original lyrics as English (likely due to a few English loanwords or the Latin-based translation text). Consequently, it forces the subtitle/translation track to render as Chinese Pinyin instead of displaying my custom Vietnamese translation.

You are right. As of now, the lyric language is auto-detected based on the entire text.

For .ttml, we plan to add support for identifying the language script via metadata.

However, for .lrc (and .eslrc), since there is no standard language attribution guideline and a high possibility of multiple translations being included, handling language script detection is quite tricky.

If you have any ideas or suggestions on how to handle this, please feel free to share!
