Is there an easy way to insert special characters in a document?

Is there an easy way to insert special characters in a document?
In MS Word, you assign special characters for Hausa Language “ĀƁāɓƊɗƘƙƳƴ” and just type ‘ALT k’ to get ‘ƙ’.
We use LibreOffice a lot, and this is a big challenge while working with Writer to edit books.

Isn’t that supposed to be an OS feature? On Linux under GNOME (similar for KDE) I can define a Compose Key for all sorts of composing letters like typing ComposeKey A _ gives Ā.

In the absence of other suggestions, how about add letters in Autocorrect options with something like :k: for ƙ

In the Menu goto “Insert” > “Special Character”

The “Special Characters” selection Window might be what you are looking for.

Hope that helps.

I think he’s asking for an easier way than this method. ¯\(ツ)
