Respondus 4 supports the primary ISO characters (ASCII 1-255), which means that it supports most "roman characters" and makes it possible to create exams in Spanish, French, German, etc. The latest versions of Respondus 4.0 provides support for the Unicode UTF-8 characters including multiple byte character sets like those used in Asian, Arabic and Cyrillic languages.
There are few ways to enter UTF-8 characters in Respondus 4.
The first is to copy-and-paste the desired characters from a program like MS Word into the Respondus 4 editor. If Respondus 4 is able to retain the character after the question is saved to the file (NOT just by previewing the question during the editing stage), then Respondus 4 supports that particular character.
A MS Word .docx file with the UTF-8 characters following the Respondus Standard Format for Import, will correctly import and preview the UTF-8 characters in the latest version of Respondus 4.
A localized keyboard with Windows display language can be used for direct entry of most UTF-8 characters including multibyte character sets.
UTF-8 characters can also be entered directly with the Unicode value. For example, if you already know the code for ã is 227, you would hold down the Alt key and enter 0227 using your numeric keypad (NOT the number keys across the top of your keyboard).
