[Here](https://docs.inductiveautomation.com/display/DOC79/Keeping+Tags+Organized#KeepingTagsOrganized-InvalidTagNamecharacters) is a link to characters that are invalid in tag names. There is no way to ‘escape’ special characters in tag paths.

To expand a little more - the first character in a tag/folder name must be a valid ‘letter’ (supporting Unicode’s definition of a letter), number, or an underscore. After that, most special characters are disallowed - but `(`,`)`,`'`,`-`,`_`,`:` are specifically allowed.
