ASGI cannot differentiate between / and %2F in a URL, so we need an
alternative scheme for encoding the names of tables that contain special
characters such as /
For background, see

Some examples:
"table/and/slashes" => "tableU+002FandU+002Fslashes"
"~table" => "U+007Etable"
"+bobcats!" => "U+002Bbobcats!"
"U+007Etable" => "UU+002B007Etable"
