The TXTtoFNT(c) TECHNOLOGY let the developer to use bitmap fonts to display font in correct manner. The maximum byte cost of this technology, if the bitmap font is "K" kb and you use "n" letters, is:

K [kb] + 16*n [b] - n

(if you use the complete character set).
For example, if K=4 Kb and n=100 letters: 4 Kb + 1600 b - 100 b =
about 5,5 Kb over the simple text.

Moreover using "c" different characters from bitmap font the byte cost is about:

50*c [b] + 16*c [b] - c

For example, if c=4 letters (or symbols): 50*4 + 16*4 - 4 =
about 260 bytes over the simple text.
