Do these fonts support umlauts (ä, ö, ü) and ß? Those are very common characters in the german language.
Some of our fonts do, some don't. If you go to our dafont profile with accents turned on & preview set to show the umlauts you can get a list of the fonts from the pack that support them: https://www.dafont.com/chequered-ink.d6231?text=%E4%F6%FC%DF&a=on
This link will show all the fonts that support those characters to varying degrees.
