This is explained on p. 29 of the Isar manual, in the "Lexical Matters" section:
http://isabelle.in.tum.de/doc/isar-ref.pdf
"The syntax of string admits any characters, including newlines; “"” (double-quote) and “\” (backslash) need to be escaped by a backslash; arbitrary character codes may be specified as “\ddd”, with three decimal digits. Alternative strings according to altstring are analogous, using single backquotes instead."

Formulas may be quotes by backticks, like X=0
.
But what if a formula to be quoted contains backtick, like "f`a". Can we quote
such a formula?
