Re: [ft] Rendering chinese characters
Nice to hear that you had proceeded your first step. I have to note that the preferred typeface design policy in HongKong would be different from Hanazono Mincho, and, some documents may use HKSCS characters via PUA codepoints (Hanazono fonts may not support PUA codepoint for HKSCS), so I recommend to consider the possibility to update the application to use multiple fonts.

Re: [ft] Rendering chinese characters
Hi mpsuzuki,
using ftview ,I m able to see BMP characters,But my intention is to display
chinese characters in non-BMP plane...
when I give the following command
ftview -m '豈' font ming.ttf ,I m able to display the character as this
character belongs BMP plane...
ftview -m 'text' fontfile
In ftview ,is there any option to give 'unicode point' as argument?
(because in the place of text in ftview command ,I have to copy the equivalent
character of 0x00027267,which I am not able to.I m able copy only
squares!!! )

Hi,
Are you sure that your font file (I don't know what it is) include the
character for +0x00027267?
If you are sure, how you have checked it?

Hi,
I m using the following piece of code for rendering the Chinese

FT_Library library;
FT_GlyphSlot slot;

FT_Init_FreeType( library );
FT_New_Face( library,/usr/local/share/ming.ttf,0,face);
FT_Set_Char_Size(temp_ptr-face,16*64,16*64 ,500,500 );
slot = face-glyph;
glyph_index = FT_Get_Char_Index(face,0x00027267);
printf(Glyph index is %d is \n,glyph_index);
}
when I printed the glyph_index ,it is zero...bt if I use 0xF900 instead of
0x00027267 ,I m able to see the Chinese character..
My doubt is why the FT_Get_Char_Index does not display Chinese character
for Unicode value 0x00027267?
Is that the problem of font file ,I m using?
Why I m nt able to get the glyph (or charmap) of 0x00027267 and similar
values?
Please help me..
Thanks in adv.

Re: [ft] Rendering chinese characters
Hi,
At present, ftview does not receive UCS codepoints via hexadecimal expression.
But, as you already checked that FT_Get_Char_Index() fails for non-BMP
character,
what you should try is NOT the search a character by the character codepoint.
Searching a character by some codepoint always invokes the FT_Get_Char_Index().
So it does not give any new information. What you should try is
1) the font has non-BMP cmap (mapping table from character codepoint to glyph
index), or not?
2) if non-BMP cmap is included, what kind of glyphs are included in the font?
To check 1), please try ftdump.
In the case of BMP-only font, the result would finish like:
[...]
charmaps
0: platform 1, encoding 0, language 0
1: platform 3, encoding 1, language 0 (active)
It means, platform 3 (=Microsoft) encoding 1 (=UCS2), so no mapping tables for
non-BMP characters are included. There is no way to show non-BMP character with
this font (even if the font producer inserts any glyph, we cannot know that it
is related with non-BMP character).
In the case of not-BMP-only font, the result would finish like:charmaps
[...]
0: platform 0, encoding 3, language 0
1: platform 0, encoding 4, language 0
2: platform 1, encoding 0, language 0
3: platform 3, encoding 1, language 0
4: platform 3, encoding 10, language 0 (active)
You can find that there is UCS4 cmap (platform=3, encoding=10), so there might
be some non-BMP character.
---
After knowing the font includes non-BMP character, please show the glyphs in
the font with ftview, and push F12 key endlessly until the end of the glyph
index. When you reached the end of the glyph index, push F7 key to back 10
glyph index, and search the last CJK ideograph - you may be able to guess the
coverage of CJK ideographs, because huge CJK fonts including non-BMP characters
often order their glyphs by UCS codepoint at the quite large glyph index.

Hi mpsuzuki,
using ftview ,I m able to see BMP characters,But my intention is to display
chinese characters in non-BMP plane...
when I give the following command
ftview -m '豈' font ming.ttf ,I m able to display the character as this
character belongs BMP plane...
ftview -m 'text' fontfile
In ftview ,is there any option to give 'unicode point' as argument?
(because in the place of text in ftview command ,I have to copy the
equivalent character of 0x00027267,which I am not able to.I m able copy
only squares!!! )
Thanks in adv...
Thanks Regards,
Daya

In addition, if you're working on Unix like systems, please try ftview
command.
It will show the glyphs in the font without consideration if they are
accessible via some character code,
so it might be helpful to know if the font supports non-BMP characters.

Hi,
Basically, if glyph index returned by FT_Get_Char_Index() is zero,
the font is expected to lack the glyph for the character code passed
to FT_Get_Char_Index().
