In our modules, we have covered how to read and write regular expressions that use numbers, special characters, and letters from the Roman alphabet (A-Z). But what about characters from other languages? This is also possible, and there are different ways to do it!

Now, most character sets and alphabets have their own ranges in Unicode, so you can simply grab the first and last code and use that, as long as your system supports it. However, Japanese uses three different "alphabets," one of which is derived from Chinese. Additionally, Japanese users will sometimes use English words when they are talking about something specific, quoting something written in English, or if there isn't a good translation for it.
