Working with double-byte regex expressions with Python3

As part of my project Self Hosted Zapier Alternative; I am having to deal with doing regex searches against the three Japanese written forms, Kanji, Hiragana and Katakana.

Fortunately this is a common problem. So I have found some references for this. Also one of my favourite tools for developing regex expressions, Regex101, also offers support in this area.

I found this useful Github Gist.
You should also check the gist directly as there are some follow up comments and additions. See here

Using Regex101 I was able to come up with the following expression.


This will successfully match a string such as:
「渋11 渋谷駅行き・駒沢大学駅前」でタッチしました。  
Resulting in the following three groups.
busname = 渋11
destination = 渋谷駅
boardedat = 駒沢大学駅

If you are working in PHP you can also use the following:
\p{Han} (Using Chinese to match Kanji)
