📜 Why use Chinese words separator? "A study from 2008 showed that if spaces are placed after what are commonly regarded as words in Chinese, Chinese native speakers' reading actually becomes faster and easier." -- Julesy 📺 https://www.youtube.com/watch?v=kCSe3dgGVMQ

📈 If the introduction of spacing provides measurable benefits for native Chinese readers, these benefits are likely to be even more pronounced for non-native readers.

🚀 LATEST VERSION OPTIMIZATIONS:

⚡ Ultra-Fast Word Separation:
The word separator processor now uses a tiny 160 KB memory lookup! Previously, reading HSK levels from a large file caused memory usage to spike up to 100 MB. Now HSK info is embedded directly into the code.

📉 Lightweight Memory Footprint:
CWS dictionary memory usage can now drop to just 26 MB! Even with around 175K words (compared to 120K in other dictionaries), you can make CWS extremely lightweight by having it read definitions from the database rather than files.

To enable: Go to CWS Settings ⚙️ and tap the *Save the dictionary to database* button. Memory footprint drops from 108 MB to 26 MB!
