Tags are zero-width Unicode characters just like the byte-order mark
U+FEFF. Note that the tag uses a completely different set of characters
than the normal Latin alphabet. Similar to how in UTF-8/UTF-16 it is
possible to find in O(1) time the beginning of a character, in this RFC
it is always clear if a character is part of a tag or not.
