Can I get cootdot font

edit

General comment: Fonts have nothing to do with applications, Libre Office or MS Office. Fonts are managed and installed in the operating system.

Not sure that you could in 2017, but today you can. I downloaded and tested it in Writer, and everything is as expected for reasonable quality free stuff:

• Upper and lower case characters from English alphabet, numbers and the common punctuation looking good.
• International characters missing, and replacement font needs tweaking. Autoselection fails to find a useable replacement.

Fontspace lists it as freeware, and it looks like the donation link will go to the creator, should you feel like contributing something.

• Download.
• Open downloaded file to install on system.
• Restart LO app to reload fonts.
