Duolingo Unicode Normalizer per blmage

Duolingo expects answers and word searches to be NFC-normalized strings (see the Unicode Normalization FAQ).

But, depending on the input method, those values may contain decomposed characters, making them internally different from their normalized versions.

For example, the Vietnamese word một (one) can be written in (at least) 3 different ways:

1. một : m \u1ED9 t (NFC)
2. một : m \u00F4 \u0323 t (VN keyboard)
3. một : mo \u0323 \u0302 t (NFD)

The extension aims to prevent false positives in typo detection and fix word searches by automatically normalizing relevant inputs.
