Related issue filed in the Flutter repo: flutter/flutter#132711

Since updating to Flutter 3.13.0, my web release builds are now failing.

This seems to be caused by using this package, but I'm not certain if it's only this package or all custom font packages.

The error message when building is:

Codepoint 32 not found in font, aborting.

Target web_release_bundle failed: IconTreeShakerException: Font subsetting failed with exit code 255.
