With the release of Unicode 8.0, U+E0020–U+E007E are no longer deprecated characters. 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". 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".
With the release of Unicode 9.0, U+E007F is no longer a deprecated character. (U+E0001 LANGUAGE TAG remains deprecated.) The release of Emoji 5.0 in March 2017 considers these characters to be emojis for use as modifiers in special sequences. The only usage specified is for representing the flags of regions, alongside the use of Regional Indicator Symbols for national flags. These sequences consist of U+1F3F4 🏴 WAVING BLACK FLAG followed by a sequence of tags corresponding to the region as coded in the CLDR, then U+E007F CANCEL TAG. For example, using the tags for "gbeng" (🏴) will cause some systems to display the flag of England, those for "gbsct" (🏴) the flag of Scotland, and those for "gbwls" (🏴) the flag of Wales. Sequences representing other subnational flags (for examples US states) are also possible using this mechanism, but as of Unicode version 11.0 only the three flag sequences listed above are "Recommended for General Interchange" by the Unicode Consortium, meaning they are "most likely to be widely supported across multiple platforms".
