The copyright information for the Handler and Provider classes was copied from another piece of code. I'm uncertain if this approach is appropriate.

Thank you for this amazing contribution. But before I can merge it, do you know what license governs these icons? We can only use icons whose license allow free redistribution.

These SVG icons are sourced from an open-source project called Bytedance IconPack, which is under the Apache-2.0 license. However, the SVG icons couldn't be directly converted to font files. I wrote a script to process these SVGs, and then used the online tool at https://icomoon.io/ to convert the processed SVGs into font files. I have open-sourced the processed SVGs.
