"NO GLYPH" problem

When I export my font and use it in other software, there is “NO GLYPH” every time to word get too heavy and need to automatically enter.
How to fix it? There is a name of these hyphen that i can design?
Thanks in advance for the help!

That’s because you don’t have “hyphen” glyph in your font.
Add it will solve your problem.

I do have a hyphen glyph designed. Do you know what is the name in the system of this specific one? (I have the “hyphen” one and wonder if there is another one that i need)

how does it look if you use another font?

How did you install your font ?
