Problem
When typing Chinese characters using an IME (Input Method Editor), the language detection was frequently incorrect, often detecting the text as English instead of Chinese.
Root Cause
The language detection was triggered during the IME composition process (while the user is still typing), leading to detection of incomplete text fragments.
Solution
Implemented IME composition event handling to prevent language detection during composition:

✓ Tested with Chinese IME input
✓ Language is now correctly detected as Chinese
✓ Works with dynamic translation feature
