#32 Adding glyphs to a font

[Jason Earrame]

Hello,
I need some help understanding how to do something.

I took over managing a website, https://www.signxing.com/product/dog/. If you look at that page and select an image to go on the sign, all of the images are being drawn from a font that was obviously custom made. The owner would like me to add new images to the list and I have figured out that I will first need to add the images as glyphs to this font. I installed FontForge and pulled up the ttf version of the font and clicked on the next empty space and imported an SVG of the new image. So far so good, but then I try to save my work using the generate font button. It gives me a couple errors.
"The font contains errors. Self intersecting, Missing Points of Extrema, Too Many Points"

If I review the errors, it lists all of the dog glyphs, and I know the font was working. If I hit generate and then go view the font with a viewer, it is blank where the original shows the dog fonts.

I am a beginner at font creation and editing. I have nearly 100 glyphs to add to the font. I attached the original forn.

Also, what encoding should I choose?

Thank you,

I believe that I found at least part of the answer. If I start with the .svg file rather than the .ttf I am able to add the new glyphs. When I generate font, I still get the same errors, but the completed fint is viewable.

Self intersecting and Missing Points of Extrema can be fixed just with one click of button. If you generate the font and the errors appear (this can be accessed also Element -> Validation -> Validate), just click the error (the red written text). This will get you to the glyphs. It will write what problems are there and to these two errors a "Fix" button in the middle will appear. Just click it (sometimes it takes more clicks) and errors are fixed.
Too many points error could mean, that you have more points in the vector file on one place, or are there too many points and FontForge can't import so many. Actually the first problem is more common.
Font contains errors error... Well, I have never met this one. It could mean everything. Problems in Kerning, Naming and much more. So I can't help you with it.
It doesn't depend on encoding a lot till you use chinese glyphs or something like that. I would recommend the ISO Unicode BMP or Full.

I hope it helped you at least a bit. You waited for it a whole year so...
