🚧
Tags with spaces will have - added between words.
Creating a variable with the tag of "brand new tag" will result in a variable being created with the tag "brand-new-tag"

🚧
Creating variables that have a pre-existing tag will have _X appended to the tag name.
If a variable is created with the tag set to "tag-name-example" but another variable already exists with that same tag, the new variable will still be created, but will be created with and underscore and the next available number appended to the end of the tag, ie: "tag-name-example_1"
