CSS ID contains inappropriate characters

[dmhendricks]

• WordPress 4.9.7
• PHP 7.1.17
• Titan Framework 1.12.1 (Composer)

While this appears to be valid HTML5, is it desired to have non-alphanumeric + underscore + hyphen characters in an ID attribute value?

I was just curious, wondering if it has any jQuery or CSS implications (for example, I don't think CSS would like it if there were square brackets?) This example has parenthesis:

Thank you,
