Hi!

Glyph transformers made some characters narrower and made some characters bolder.

I only want to make characters bolder. What did I wrong?

When a contour has the wrong direction, the bold transform will behave the opposite of what you expect. It may make parts narrower instead of thicker.

To fix this, first make sure all contours use the correct direction, and then apply the Bold glyph transformer again.

Validate fixed the problem but some charachters’ holes filled after made it bold.

It’s possible that Validate removed some internal contours by accident. If that happens, you’ll need to manually correct those glyph outlines.
