%R
  Display a roman number.

%s
  Display a string. If the value is not a string, it will display it as
  whatever type it is.

%T
  Only valid if this puzzle set uses MBCS. This is like %c but uses all of
  the bits to make a TRON-32 character code. If the code is less than 256
  then this is the same as %c. (This is not fully implemented or tested.)

%u
  Display a unsigned decimal number.

%x
  Display a unsigned hexadecimal number in lowercase.

%X

14 (\i) = Icon
15 (\b) = Horizontal rule
16 (\q) = Quiz button
27 (\T) = Multibyte character escape; used only during parsing
30 (\d) = Data
31 (\x) = Next byte is a character to display as graphic

Codes 32-255 are displayed as is, but characters 1-31 cannot be displayed
as a graphic unless a \x escape is present.

A few additional codes are only used in MBCS mode:

27 (\T) = Multibyte character escape; used only during parsing
127 = Internal representation of %
254 = Plane shift
255 = Switch to ASCII until the next plane shift (internal only)
