Full uincode support
There are a large number of Unicode characters that cannot be entered into Squareline These Unicode characters are useful, they are used as a variety of icons, the characters are more convenient than pictures, the zoom in and out is lossless, and the color modification is easy.
For example, \udb81\udfa9 and \udb82\udccd, two characters that appear as cars in the nerdfont font, I can’t type them into squareline
Modify the.spj file of the related project directly, but this is tiring
The use of characters as icons is common among vim users, please refer to GitHub - ryanoasis/vim-devicons: Adds file type icons to Vim plugins such as: NERDTree, vim-airline, CtrlP, unite, Denite, lightline, vim-startify and many more
For example, I need to display a fuel tank icon, which has two states of yellow and green. If it can be realized with characters, why not do this? It is very convenient to modify the color of the text, and it is also very convenient to modify the size of the text.
