In current version GNU Unifont, there are the following problems.
(1) Space (U+0020, U+00a0, etc), TAB is not displayed by the blank.
These displayed as [SP], [NBSP], [HT].

Therefore, the menu and the title, etc. are very hard to read.

Other space like characters (U+00a0, U+3000 etc.) are similer.

(2) Because Rockbox doesn't support the combination of the characters, the glyph change of character of combining diacritical marks are not significant.

When the characters changed by GNU Unifont 20080820 -> 20080827 was checked, the correction of combining diacritical marks and space like characters was most.

Thus, I think that I need not change 16-GNU-Unifont.bdf (this is based on
GNU Unifont 20080820).
