Revert "console ASCII glyph 1:1 mapping"

This reverts commit 1c55f18717304100a5f624c923f7cb6511b4116d.

Ingo Brueckl was assuming that reverting to 1:1 mapping for chars >= 128
was not useful, but it happens to be: due to the limitations of the
Linux console, when a blind user wants to read BIG5 on it, he has no
other way than loading a font without SFM and let the 1:1 mapping permit
the screen reader to get the BIG5 encoding.
