Userdefined macro keys for special characters

[H4rryK4ne]

What is the current behavior?

If a special character (like german umlauts) is typed the encoded char is placed. To be platform independend one has to sanitize the special char (e.g. ä to {\"a}).

What is the expected or desired behavior?

When the special char is typed, it shall be replaced with the sanitized form. In the settings could be a page where the replacements can be set.

Please provide use cases for changing the current behavior:

When ä is pressed, {\"a} is written, automatically.
