Commas are used to separate a list of things, but matters are complicated when an item in a list also has a comma. How can you tell if it indicates the next item in the list or not?
I’ve discovered that WordPress does not play nicely with taxonomy names (Tags, Categories, etc) that contain commas. You can enter the name correctly in the taxonomy editor screen, but when you save a post that has such a taxonomy term, WordPress will create multiple new taxonomy terms named by the words separated by the comma(s) and assign the post to these instead of the original. This is frustrating.
Despite being aware of the issue, after accidentally doing so several times I decided that it might be better to use a character that LOOKS like a comma but isn’t a basic comma.
I propose using the Single Low-9 Quotation Mark.
This is a regular comma , and this is a single low-9 quotation mark ‚
