Patch 8.2.0867
Problem: Using \{xxx} for encoding a modifier is not nice.
Solution: Use \<*xxx> instead, since it's the same as \<xxx> but producing a

To use the double quote character it must be escaped: "<M-\">".
Don't use <Char-xxxx> to get a utf-8 character, use \uxxxx as
mentioned above.
! \{xxx} like \<xxx> but prepends a modifier instead of including it in
the
! character. E.g. "\<C-w>" is one character 0x17 while "\{C-w}" is four
bytes: 3 for the CTRL modifier and then character "W".
