Fix to issue #2747.
The slowdown was caused by complex lookarounds used to avoid extracting numbers from percentage expressions in certain patterns. But since in English this kind of filtering is not implemented, they do not seem to be necessary and have been removed.
Test cases added to Chinese NumberModel and CurrencyModel.
Another issue observed is that long numbers in Chinese characters do not seem to be resolved correctly.
