A EOT can't be unpacked

[mikekaganski]

This EOT, generated by PowerPoint 2016, fails to be extracted by libeot:

font1.zip

This is the original font:

Font_Shlop_1.zip

Unrelated: the font is marked for limited use; but it is from https://typodermicfonts.com/downloads/ , where it is listed as one of "free commercial use fonts".
