Don’t know. In a different context (haha) I’d say a nazi greeting.

"combining" means a combining accent.

In case you’re on MacOS and copied the text from e.g. a PDF, MacOS 
decomposes many (all?) accented vowels, like u + combining trema instead 
of a proper ü umlaut glyph, and that can cause missing or displaced 
accents, depending on the font.

Similar with additional space “glyphs” that are often missing in fonts 
and cause warnings like this.

Are you missing any characters where this long stroke should appear?

I wouldn’t call that ignorance – you can ignore a lot of warnings if the 
output looks good enough.
