The "grayed out" left and right arrows in the Symbol 11 font were
added in PalmOS 3.2, and so aren't available in 3.1 and older.

BTW, names for these are defined in Chars.h:
// Characters in the 11 point symbol font. Resource ID 9004
enum symbol11Chars {
// ...
symbol11LeftArrow,
symbol11RightArrow,
symbol11LeftArrowDisabled, // New for Palm OS v3.2
symbol11RightArrowDisabled // New for Palm OS v3.2
};
