Are overlapping corners in a ttf valid?

Hello,

I'm currently trying to create a pixel based font and have created all of the required glyphs. I would now like to generate a ttf file; however, I get multiple "Self Intersecting" validation errors.

I know that many of the outlines for my characters have overlapping corners, but since I want the characters to seem like they are made from squares/blocks/pixels, it seems necessary for me to do so.

Example:

(background and text colors are interchanged).

I have gone ahead and generated the ttf file anyways and have tested the font and it seem to work.

My questions are:
- Is it alright if I ignore these errors and generate/use the font anyways?
- Are there any possible issues that may arise from doing so?

Thank you,
TheScripts

If the directions are set uniformly you shouldn't see basic rendering problems but you may see more subtle issues

Thank you for the response.

I've done a fair bit of testing with the generating font and haven't seen any issues; so I'm happy enough with the results and am fine with ignoring the errors.
