And attached is the font after generating it again using fontforge. This version seems to work well in Sigil at least under Linux/KDE (after tweaking the css url to match the new name).

It is many times useful on Windows and MacOS to set the env variable to create a debug log file in your home directory and launch sigil and then after closing sigil, look at the debug output generated by Sigil or Qt. Just do not forget to unset that env var.

Ps: just use Sigil GetInfo to get file size info for any file in Sigil.

PPs: given the number of broken free fonts out there, validating a font before embedding it with a good font utility is probably a good idea.
