I am new to creating/editing fonts. I want to create a font with custom symbol for "glyph not found". I have downloaded FontForge as it seems to be a widespread free font editing program. I was hoping first U+0000 NUL, Default Character would be that, but it seems that I was wrong. I cannot find any info on how to make your own "glyph not found" symbol on google, maybe here somebody could help?

    U+0000 is a defined character and not an un-defined one, so no, that will not work. .notdef is a unique glyph on its own and does not have a Unicode assignment. That would defeat its purpose. See typedrawers.com/discussion/comment/35074#Comment_35074 (you may want to read the entire thread). – usr2564301 Jul 5 at 9:03

So far as I'm aware there is no “glyph not found” character. Different programs use different graphic presentations. An empty narrow rectangle is a common rendering, but not the only one. It could also be a rectangle with a question mark in it or with the code number of the character, in hexadecimal, in it.

From the Unicode Spec:

The Unicode glossary entry says:

It often is shown as an open or black rectangle.
