Exportin OTF with custom Glyphs

Is it possible to export an OTF where specific latin glyphs arent included?
When i export it the glyphs i removed are replaced with a standard glyph.
Specifically im trying to get rid of C,Q,W,X,Y

Which standard glyph?which app version?

If you use the Remove Glyphs filter, the glyphs should not be exported. Only exception is .notdef.

And how and why do you try to remove those glyphs. And do you see the standard glyphs?
