Working on a german project with dynamic Textfields or forms is no problem for me: there are six »Umlaute« and one ligature, that I use every day. English forms are even easier: no special characters at all (how unimaginative ;-)…
But at the moment the project’s scope is widened to East- or West-Europe, problems begin if you weren’t attentive in school: In Spanish questions start with this upsidedown questionmark, don’t they? In French there are accents, but what directions and on which letters? And does anyone had Czech or Hungarian in school?
This is for all developers, making forms or dynamic textfields for the western hemisphere (no Cyrillic or Greek characters).
Comment if something is missing and I’ll update the list.
