On Arch Linux that currently has the mix of KDE 4/Plasma 5.
As a Web Developer I need to enter some Unicode Characters into Chrome for testing. I do not have a consistent set of character that I need to enter because, as an American, I usually have trouble convincing other people (my boss) that Unicode is worth paying attention to. I'd prefer to have a visual tool that allows me to select characters, without navigating to a website.
What tool can I use to do this? being that arch is minimalist is there any software I need to install that I might not have yet (don't assume that some thing that normally ships with KDE or Xorg is installed)?
