[oqgqulke] Capitalized punctuation

Capitalize `{|}~ to get @[\]^ according to the ASCII table (alter 1 bit).  DEL maps to _

Apply a similar transformation to the digits 1..9 to get !"#$%&'() and 0 maps to space.  This is almost, but not quite, the shifted numerals on the keyboard.  Beyond 9, we also have :;<=>? shiftable to *+,-./

Shift the other way to map 0-9 to P-Y.

  ! " # $ % & ' ( ) * + , - . / 
0 1 2 3 4 5 6 7 8 9 : ; < = > ?
