Reproduction steps:
1. Open attached project
2. Check the Fonts folder in the attached project and make sure they are not previously installed on your OS
3. Observe the Game View rendering of the text (part of the text: "this bit of text" isn't bolded)
4. Install these fonts on your system from the Fonts folder (right-click install from an explorer window)
5. Once installed, check back in Unity and observe that when the Game View refreshes, the part of the text: "this bit of text" is now bolded.

Actual result: Part of the text: "this bit of text" isn't bolded.

Expected result: Part of the text: "this bit of text" should be bolded.
