nanogui: Thread: White space.

Has anyone noticed that the space character (0x20) is not showing up correctly (spacing)?

I've been using a Microsoft ttf file and decided to experiment with other font types.
I've been doing this on linux and that's when I realize I've been using a microsoft fixed size ttf file.

Is this just my system? Or has this been known all along? I'm using type 2 ttf fonts.

Thanks,
--Jr.

I've been digging and realize that the font render might be the problem.

I've pulled the font library 
n022004l.pfb -URW-Nimbus Mono L-bold-r-normal--0-0-0-0-m-0-iso8859-1
and did a GrGetGCTextSize on several characters. This should be a monospace font but I didn't get that:
char: 20  w:11 h:0 b:0 
char: 2a  w:12 h:13 b:13  
char: 4e  w:13 h:12 b:12 
char: 54  w:12 h:12 b:12 
char: 52  w:12 h:12 b:12 
char: 4f  w:12 h:12 b:12 
char: 4c  w:12 h:12 b:12 
char: 45  w:12 h:12 b:12 
char: 52  w:12 h:12 b:12 
char: 44  w:12 h:12 b:12 
char: 41  w:12 h:12 b:12 
char: 54  w:12 h:12 b:12 
char: 41  w:12 h:12 b:12 
char: 20  w:11 h:0 b:0 

I'm using a cvs source I pulled on May 06. Have this been identified before? Has there been any changes that would fix this in later updates?

Thanks,

I've seen cases of the TTF space character not having actually
been implemented, that is, its up to the applications programmer to
provide space between characters.  That said, there could be
issues with the display code when the height is 0, perhaps
that special case causes the code to skip the display completely...

No.

I see... I think I have a work around.

I've been trying to locate the header info to try a newer release of freetype2. I've getting a "buffer" variable undefined.
Has anyone got this fixed? (I have cache disabled).
