libobs: Use byte sequence for non-breaking spaces

Use explicit UTF-8 byte sequence for the "no-break space" character.

Prevents issues with certain editors, and fixes the following compiler
warning on Visual C++:

warning C4819: The file contains a character that cannot be represented
in the current code page (X). Save the file in Unicode format to prevent
data loss
