| Subject: Revert "console ASCII glyph 1:1 mapping" |
| |
| 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. |
