Word description
Reads from the input string until the next occurrence of " or """, and appends the resulting string to the parse tree. String literals can span multiple lines. Various special characters can be read by inserting Character escape codes. For triple quoted strings, the double-quote character does not require escaping.

Examples
A string with an escaped newline in it:

USE: io "Hello\nworld" print
Hello world

A string with an actual newline in it:

USE: io "Hello world" print
Hello world

A string with a named Unicode code point:

USE: io "\u{greek-capital-letter-sigma}" print
Σ

A triple-quoted string:

USE: io """Teach a man to "fish"... and fish will go extinct""" print
Teach a man to "fish"... and fish will go extinct
