I hope you'll consider switching to svg icons. I recently upgraded my custom theme from Font Awesome 4 to 5, and I discovered that FA 5 does not work with GDI. GDI is enabled by default when using Chrome on older operating systems, such as Windows XP through Windows 7. Font Awesome has known about this problem for more than a year, but they do not consider it a priority. I disagree since icons are needed for basic website functionality in many cases.

There are many articles online explaining why svgs are superior to icon fonts.
Thank you for providing the information. We really appreciate you taking time and share your idea.
