--- Comment #2 from Sagawa sagawa.aki+winebugs@gmail.com --- Update, the upper bound seems to be related to the product of height and the max character width.
Tahoma with lfHeight 20,561: tmHeight 20,561 * tmMaxCharWidth 41,762 ---> 858,668,482
MS PGothic with lfHeight 20,864: tmHeight 20,864 * tmMaxCharWidth 41,158 ---> 858,720,512
Arial with lfHeight 18,976: tmHeight 18,976 * tmMaxCharWidth 45,257 ---> 858,796,832
These values seem to be very similar, although I haven't figured out the formula. Any suggestions would be appreciated.
