If anyone has any objections, please let us know. --------------------- From: Samuel Thibault upstream commit: c0b7988200a82290287c6f4cd49585007f73175a 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.
