the comma in Chinese is different from that in English. But they are too similar.
correct English comma
incorrect Chinese comma
As a non-English user, we have to switch the input quite often. If I type a Chinese comma in a large block of code by mistake, my god! sometimes it kill a lot of time to find what is wrong.
I previously write a suggestion to wolfram support to make Chinese comma stand out, so I can easily catch it. They claimed that they will consider it.
But it is already M11 now, things are even getting worse. The commas are more similar in the new font!
So I can not wait, is there a way to customize syntax highlighting to make a particular symbol colored, bigger, or whatever to make it stand out?
