Tags is a Unicode block containing formatting characters.

U+E0001, U+E0020–U+E007E, and U+E007F were originally intended for invisibly tagging texts by language^[2] but that use is no longer recommended.^[3] All of those characters were deprecated in Unicode 5.1.

With the release of Unicode 8.0, U+E0020–U+E007E are no longer deprecated characters. (U+E0001 LANGUAGE TAG and U+E007F CANCEL TAG remain deprecated.) The change was made "to clear the way for the potential future use of tag characters for a purpose other than to represent language tags".^[4] Unicode states that "the use of tag characters to represent language tags in a plain text stream is still a deprecated mechanism for conveying language information about text.^[4]
