You got it wrong. European Latin-based scripts are not identical. They have, besides the basic Latin set of letters, different diacritics. The original Latin alphabet has/had less than 26 letters, and the European languages had to adapt (either by supplement it, or by expressing sounds through combinations of existing letters). Now, a font may or may not have all the European letters, but that makes it merely incomplete from a language's perspective, not that it belongs or not to a given language.
