Is there any harm done if I use a hyphen in a font name?

Chris Lozos

Will it break anything if I do?

I have loads of fonts with hyphens in their names, so I guess the answer is "No."

I  named my one font "DigitaltS-Lime" and found that some programs (for example Scribus) treat part after hyphen as a style name ("Lime").

A hyphen has a specific meaning within a font's PostScript name ID, so having a hyphen elsewhere in the name can be a problem: you'd have to omit it from the PS name, and could end up with that name being displayed in some situations, as 'gluk' noted.

I not tested - DigitaltS-Lime is OpenTypeSVG font, InDesign and Illustrator don't support SVGinOT technology.
But with failback one color glyphs should work in both programs.
Font with free OFLicense is available here: DigitaltS-fruits

It looks like a problem in your font, as your font has font family DigitaltS-Lime and font subfamily Lime.

Thank You @Erwin Denissen, I know exactly where is (small) problem in my font. Simply in auto-generated names Fontforge used as subfamily part after hyphen and not as usual weight name "Medium" (when FontName and FamilyName are equal).
As far as I know only some programs use SubFamily name.
I show it as example for some harm, is someone use hyphen in font name
