DTE (Dual Tile Encoding)
Certain platforms, after encoding the alphabet, numbers, and
punctuation as single tiles, use what is left of their 255
possible character table entries as DTE (Dual Tile Encoding) and
MTE (Multiple Tile Encoding) values.
In the case of DTE this means that some of the remaining hex
values are assigned common "dual-tiles".
Example:
In Final Fantasy 2 (US) the following hex values are SOME of the
dual-tiles representing common character pairs.

If DTE is used extensively, it makes determining the encoding
table very difficult because guesses would have to be made about
how DTE is used.
