Windows 10 October 2018 Update is reportedly causing font errors on Foobar2000, a popular freeware audio player. According to reports, Foobar2000 has broken fonts after installing Windows 10 October 2018 Update (version 1809) but unlike the deletion bug, this is not a critical issue or a dealbreaker.
According to a thread on a forum, the rating stars in Foobar2000 are not working anymore after installing the Windows 10 October 2018 Update. It appears that Windows 10 version 1809 is having font substitution or front font fallback issues where the operating system fails to replace the missing characters from one font with another.
Several users have also documented the problem on Reddit and Microsoft’s software engineer revealed that this is could be a substitution or font fallback error.
“Ah, that to me is glyph substitution, or font fallback per my friend on the font side of the world. Font substitution to me is entirely replacing the chosen font with a different font, versus fallback – picking up characters/glyphs from other possible font sets,” he writes in a Reddit post.
“I’m using Segoe UI, the same font as always with my foobar2000 setup and all looked fine on 1803, things literally broke with the 1803 -> 1809 update,” a Reddit user explains.
It’s not known how many apps are having this issue but judging from the number of reports, this is not a widespread bug and the majority of apps such as Office appear to be unaffected.
