WOLFRAM LANGUAGE TUTORIAL
Non‐English Characters and Keyboards
If you enter text in languages other than English, you will typically need to use various additional accented and other characters. If your computer system is set up in an appropriate way, then you will be able to enter such characters directly using standard keys on your keyboard. But however your system is set up, the Wolfram Language always provides a uniform way to handle such characters.
Some common European characters.
Here is a function whose name involves an accented character.
This is another way to enter the same input.
You should realize that there is no uniform standard for computer keyboards around the world, and as a result it is inevitable that some details of what has been said in this tutorial may not apply to your keyboard.
In particular, the identification for example of Ctrl+6 with Ctrl+^ is valid only for keyboards on which ^ appears as Shift+6. On other keyboards, the Wolfram System uses Ctrl+6 to go to a superscript position, but not necessarily Ctrl+^.
Regardless of how your keyboard is set up you can always use palettes or menu items to set up superscripts and other kinds of notation. And assuming you have some way to enter characters such as , you can always give input using full names such as \[Infinity].
