Conversion changes writing systems. Translation changes language.
If a sentence is 我学习中文, a Traditional conversion can produce 我學習中文. An English translation would be "I study Chinese." Those are different products. ChineseDocConverter does the first job.
Why the mix-up happens
Both tasks start from a Chinese file. Marketing pages sometimes say "translate to Traditional Chinese." In publishing, that usually means convert characters, maybe adjust a few regional words, not rewrite the meaning for a new language.
What a converter will not do
- It will not turn Chinese into English, Japanese or Korean.
- It will not localize jokes, legal disclaimers or marketing slogans.
- It will not decide whether 后 should become 後 ("after") or stay related to 后 in names and rare uses without dictionary context.
Use the text converter when the language is already Chinese and only the character set should change. Hire a translator when the reader does not read Chinese at all.
