The forward single quote (39, 0x27, 047) is not special in any way
according to RFC822.  The grammar is convoluted because some things are
special in some places, but here are some basic elements.

     ALPHA       =  <any ASCII alphabetic character>
                                                 ; (101-132, 65.- 90.)
                                                 ; (141-172, 97.-122.)
     atom        =  1*<any CHAR except specials, SPACE and CTLs>
     CHAR        =  <any ASCII character>        ; (  0-177,  0.-127.)
     CTL         =  <any ASCII control           ; (  0- 37,  0.- 31.)
                     character and DEL>          ; (    177,     127.)
     specials    =  "(" / ")" / "<" / ">" / "@"  ; Must be in quoted-
                 /  "," / ";" / ":" / "\" / <">  ;  string, to use
                 /  "." / "[" / "]"              ;  within a word.

Most things are built out of atoms.

Well, in that example you must note that the period is special.  It must be
quoted in certain places.
