Hi,
In the table "Some of the things you can put in a Double-Quoted String" there seems to be a typo as follows :

In your Table is :

\L lowercase all letters until \E 
\U uppercase all letters until \E 
\Q Backslash quote all nonletters and nonnumbers until \E 
\E Stop \U \L or \E 
It seems that the line \E Stop \U \L or \E  should read 
\E Stop \U \L or \Q . 
Otherwise it means the \E stops it self .
