beside an appropriate font?

Thanks,

	Yes.

	I've sucessfully displayed text in UTF-8 by using TTF fonts.

: Hmm.. Thanks.  Does your mentioning TrueType fonts only mean that BDF fonts
(if
: I remember correctly, these are supported) cannot be used for such a text?


I can't remember if I answered you yet or not.  Currently, the Microwindows
builtin fonts use a byte-sized index, making BDF fonts unsuitable.  However,
this would be very easy to change.   The reason it hasn't yet is that the
index table per builtin font would be quite large, and we're trying to keep the
size
of the builtin fonts down...  Take a stab at adding it if you want the feature.

Hi all:
  I had made a Chinese(GB2312) build-in font in Micro Window tentatively, and it can be display nomal. Some .c file need to be modified. It's not difficult.

Great.  Could you send me a "diff -urN" patch when completed?

Greg

Guo,
    I have added your patches into the upcoming pre9 release.

Regards,

Greg

: Of course! You and other mail-list people give me a lot of helps before. I
only use one 12x12 font, so program is very simple and need your advice.
: Background: GB2312 is Chinese nation standard of  Chinese encoding. Last month
a new standard GB18030 had been announced and will be supported by every Chinese
version OS soon, but I cannot get encoding rules and fonts now. So I only test
old GB2312. One Chinese char has 2 bytes, first byte is high byte and called QU,
2nd one is low byte and called WEI. QU >= 0xA1 and QU<= 0xF7; WEI >= 0xA1 and
WEI <= 0xFE. The order of char is (QU - 0xA1) * 94 + (WEI - 0xA1), means one by
one. 94 = 0xFE - 0xA1 + 1.
:   I got a GB2312 12x12 font, each char is 2X12=24 bytes, 2 bytes is 12 bits;
12 is lines. I code a simple execute file and covert it to a compact format,
that cover each 4 bytes into 3 bytes. Then translate it to C array format and
redirect to font/gb12dat.c file. add it to Makefile.
:
:   I modified 2 files, engine/devfont.c and driver/genfont.c, Include examine
Chinese char, char width calc, and char bitmap.
:   I modified default font  with Fixed one in /nanox/srvmain.c because it look
better when mixed Chinese and English that use 6*13 English font and 12x12
Chinese font.
:   Last, it is running.
:   Sorry for my English.
