User customizable ambiguous characters for Unicode Highlight

[nisshymura]

I would like to set my own customized list of additional abmiguous unicode characters to be highlighted.

As a person writing CJK characters daily, I have been using Highlight Bad Chars extension to avoid the annoyance that arises from the ambiguity of unicode glyphs. I'm very happy to see the latest vscode comes with a similar feature integrated, but I feel sorry to find that the list of ambiguous characters are not customizable.
There are lots of candidates of possibly confusing sets of characters, so it would be better to ask the users to define the list of characters at their disposal.

Thanks for reaching out! How many custom confusable characters do you have, that you would like to add?

Currently I'm registering the following characters in the setting of Highlight Bad Chars extension. (I hope the unicode characters are correctly displayed.)

"highlight-bad-chars.additionalUnicodeChars": 
    [
        "￥／", 
        "；",
        "”“",
        "〜＠＃＄％＆＊＾＿＜＞｜", 
        "（）｛｝",  
    ],

They are a part of unicode variants of ASCII characters:

• parentheses (){}[]
• punctuations ;:,.
• quotations "'`'
• and other symbols found on US keyboard ~!@#$%^&*()<>?

I don't like to have them all highlighted, because some of the unicode variants are of daily use in CJK text. (The screen would look too busy, if they are all highlighted.)

I think that quote characters like U+201C “ and U+201D ” are a must-have. They sometimes appear when you paste code in Jira. Then, if someone copies that code from Jira, they get the wrong quote characters unknowingly, which break HTML. It'd be great if they're highlighted.
