It's a known issue when using optionals with unicode. There's a longer discussion here: aichaos/rivescript-js#147

I plan to fix it eventually by adding a ~Regexp command to the language that allows you to define a trigger by manually providing the regexp. You can track that issue here: aichaos/rivescript-wd#6
