Non-breaking spaces render incorrectly in Marker font

[fsih]

Expected Behavior

In order to fix scratchfoundation/scratch-render#292 , it may be necessary to replace spaces with non-breaking spaces

Actual Behavior

Non-breaking spaces look the same as spaces in all of our fonts except Marker, which seems to map all sorts of characters incorrectly

Steps to Reproduce

Type some characters such as

ÄËëÏïÖöÜü
    Ÿÿ   
        ††

into text edit in the Marker font and observe that they show up wrong

Operating System and Browser

Windows 10 Chrome

Looks like it's not just the non-breaking space. These two text boxes have the same content:

[fsih]

@cwillisf and I also found that the font mapping seems to be correct when the font is used in other applications
