Chinese text with ：［ does not align properly

[sati-bodhi]

What's the problem

The algorithm fails to work with ：　when it is followed by 「, which is very common in Traditional Chinese. Font used in this example is Noto Sans Mono CJK TC.

What's the expected result

Table columns align properly.

How to reproduce

1. Input the following and execute Ctrl + Shift + I

Update: commas ，「, semicolons ；「 when coupled with another punctuation break the alignment as well.
