v1.0.10 Translation Quality Update

We have released a major update to significantly improve the translation quality of RakuChat LINE Translator.

Key Improvements

1. Enhanced Language Detection Accuracy

Significantly improved language detection accuracy for messages containing English slang, casual expressions, and emojis.

  • Slang Support: Accurately detects abbreviations like "gonna", "wanna", "lol", "brb"
  • Emoji Support: Correctly translates messages with emojis like "Good morning ☀️"
  • URL Handling: Accurately identifies language even when URLs are included

2. Message Length Limit Compliance

Now compliant with LINE Official Account's 500-character limit, ensuring reliable delivery of long messages.

  • Long messages are automatically adjusted to fit within 500 characters
  • Smart truncation at appropriate boundaries to avoid cutting mid-sentence

3. Improved Error Message Handling

Improved handling of garbled or invalid text to prevent system error messages from being sent to users.


These improvements provide a more natural and accurate translation experience.
