broken shape font

these type of fonts, isnt actual the font. i dont use to merge shape tool into it. the fonts, when its in the small size, both on software testing and html5 web development following like on the image bug

how to solve this, without merge as one foundation of shape

It seems you export your font with CFF (PostScript) outlines. It might work better if you export with TrueType based outlines.

Alternatively check to see if the overlapping contours have the same contour direction. If the direction is opposite, then such cut-out may occur.

what do you think on this pict?

i still need bot ttf and cff

Personally, I would use Get Union of Contours, and clean up any nodes that are not on a smooth curve.

what is another solution, while others softwares may use this type of crafting

Have you checked to see if the overlapping contours have the same contour direction?

pardonly, at the moment i can’t understand your phrase. is better that you can re-explain without a complex or technical. thanks
