Regression: SpriteFont is able to read BitMap fonts but is unable to use MeasureString

Prerequisites

• I have verified this issue is present in the develop branch
• I have searched open and closed issues to ensure it has not already been reported.

MonoGame Version

MonoGame 3.8.4

Which MonoGame platform are you using?

MonoGame Cross-Platform Desktop Application (mgdesktopgl)

Operating System

Windows

Description

XNA was able to Import Bitmaps as SpriteFonts, which MonoGame is still able to do.

However, the "SpriteFont.MeasureString" method was still able to determine the width of a SpriteFont from a defined string, MonoGame currently throws the following exception:

'Text contains characters that cannot be resolved by this SpriteFont. (Parameter 'text')'

Likely an issue with the "Font Texture - MonoGame" processor

Steps to Reproduce

Load a BitMap font texture as a SpriteFont Use the SpriteFont.MeasureString method
