I *seem* to have found the problem.

It seems that once an area gets below a certain size it sums up the data, so if you have a thin area it create these kind of white areas. I want to keep it detailed but avoid this, is there anyway to do this?

My english is awful, so I don't really know what your point. :D
But, have you tried the "merge contour" command?

tried it, still looks funky :[

Try "correct connections" or "set TT/PS direction" too, maybe. :D

Hope someone else in this forum give a better suggestion after this.

no luck. now I've got even a more annoying problem. I can install the font, it shows and I can preview it even, but I cant type with it, it will just skip it and go to next font :(

Computers are not magic faeries who can sprinkle dust on a complicated drawing and convert it into a working outline font. Getting this font right is going to take a LOT of work. Optimize the outlines as a font-wide action (you’ll have to use trial-and-error to get the settings right) and then you’ll have to spend a few days (seriously, this can take days) checking and tweaking all of the outlines to fix curves that warp in on themselves, doubled points, bad inflections, curves that go the wrong way, etc.. If this is a school project and you have a really tight schedule it might even be worth starting over with something simple.

I know there is no magic button, I wouldn't expect there to be. I spent about 15min on each letter doing them by hand with kanji brush with about 30-40 tries per letter, I wouldnt have done that had I thought it was going to be easy :)

point I guess is the font itself looks great, its the preview and when installed that it looks like poo. when it's installed and you use it, it looks fantastic and I'm very happy with it.

I do not understand where FontLab glitches come into this at all. It is a buggy tool, fair enough, but it should not be blamed for everything. What do you mean you can clearly see there are no points on the inside? I can see points all around the white shape: you clearly have a path with an opposite direction inside. Look again and reconsider.

oh, yeah you're right, I stand corrected. I was referring to the right hand side more so though, it makes it look like there are those gaps inside the letter form when they are still part of the edge. I think this has to do with the anti-aliasing in preview for performance purposes maybe?

I would clean these how, however they are what make the font look convincing in my opinion. It's only preview that they turn out bad, when you use them in any program they look great, which is what makes me think its the anti-aliasing.

I thought there was a font preview function or something that would aid it in displaying for preview or smaller sizes.
