composing accented characters

[Damien Moore]

Hello and thank you for your efforts. I am using Xfce 4.10 as
distributed with Debian 8. Is there a way to compose accented characters
within Xfce? I have worked out how to do this inside LibreOffice by
redefining seldom used function keys, but I was thinking of a method of
more general application which could be used for notes, emails etc.
