Hi nimble team,
in Europe, it is very common that you serve customers in various languages. In Switzerland you must deal with at least German, English, Italian and french to be bale to deliver an application at all.
This means not only to localize the front-end but to set a language flag to each contact and to communicate with that contact in his language.
Further do you need lookups to be displayed by language-settings.
If interested I can provide you the relevant details.

If you import e.g. German Umlauts currently, all of these signed like ä, ö. ü are simply skipped by the import.

I assume that you are not able to sell out side English speaking countries without Multi-Lingual support.
