All BlueUtopia modules will accept Spanish characters. That includes broadcast email, as well entering these characters in the name of organizations, people, tags, lists, etc., in the normal course of entering and saving information throughout the application. However, the html-editor does not include these characters in the bar so if you need to enter them, you cannot look here for these characters.

á é í ó ú ü ñ ¿ ¡
There are also ways that you can add these characters directly from your keyboard in both Windows and a Mac. Here is a 3rd party resource for installing multi-language capabilities to your PC or Mac: https://www.spanishnewyork.com/spanish-characters.html
