Sandcastle hangs the browser tab when I open the demo, but I was able to grab the problem string. It is 50 69 61 75 ed ad in hex. That last character 0xAD is a soft hyphen which is normally not rendered. It definitely should not be in the label text, but also its inclusion should not cause Cesium to hang the browser.

Actually, I just realized that this already came up in #4918 (comment) but @mramato said it was fixed. Maybe they forgot to test for this specific character?

At any rate, IIRC, Label never auto-wraps text, which is the only purpose of this character, so simply stripping it from input strings should be the right course of action.

Thanks for including the Sancastle example @hemincan . I was able to reproduce this crash as well
