left_child_word_offset_or_char_leaf
– An 8-bit unsigned integer number with the following
interpretation: If the highest bit is cleared (i.e., bit 7 is zero), the number
specifies the offset,
in words, of the left child from the root of the order-1 decode tree; if the highest bit is set (bit
7 is one), the lower 7 bits give the code (e.g., in ASCII) for a leaf character.
