In pdftex you probably see nothing because it depends on the setting of
\tracinglostchars. In luatex, there was a bug, where nothing was ever
printed except in some odd cases inside math and the virtual font definition
I’ve committed a fix that checks during shipout and, with \tracinglostchars=2,
I now get this output on the terminal:
Missing character: There is no ß (U+00DF) in font cmr10!
that is not completely perfectly right, because it is not really a character at
that point, but that is mostly cosmetics, and this message is a bit easier to
comprehend than ‘Missing glyph’.
