Hi
Thanks to all for your help, but the issue is concerning all special characters like ★.
This issue was brought by Windows 10 update 1809. If you update your system with it, you'll get this issue in Lightroom, Bridge and all other applications using such characters.
It has been confirmed by other users in MS Forums, and many feedbacks to MS engineers have already been made.
One advice : don't update to 1809 !

Interesting -- I just updated to 1809 and observed the problem. According to the many other reports, update 1809 broke font substitution / fall-back, which is the mechanism in which Windows automatically uses another font to display a Unicode character that isn't in the current font:

This doesn't affect all Unicode special characters, just those that aren't in the current display font. Here's my test with LR 8.1 / Windows 10 update 1809, showing that just ★ is displayed incorrectly:

It's pretty shameful that Microsoft hasn't fixed this basic bug in over 2.5 months.
