If you use LCD components(1602, HD44780) and haven’t given up to modern OLEDs and e-ink displays, the chances are that you know the possibility of using custom characters.
I was searching for some cut-and-paste characters for a project but could not find an easy solution. For that reason, I decided to assemble an editor and library with some characters.
You can access a live version of the project here , and the source code is available on Github . After creating your characters, don’t forget to add it to the library with a pull request.
