CLONE -Adding a tag containing wildcards to all types of content works incorrectly

Steps to reproduce:
1. Try to create any content;
2. Enter into "Tag" field string containing wildcards (such as ^& ,). For exapmle: "a^ny&str in,g" (1.JPG);
3. Press "Add" button -> Characters separated tag. So 5 tags ("a" "ny" "str" "in" "g") have been added.
4. Enter into "Tag" field only spase -> "Add" button is disabled;
5. Enter into "Tag" field only "^" "&" or "," -> "Add" button becomes enabled (Press "Add" button -> Nothing has been tagged) (2.JPG).

Expected Results:
If characters (such as ^& ,) are working as separators and it's correct then "Add" button for all of them used without other symbols should be also disabled as it happens when only space is used as tag.
