Fonts do not display characters or Glyphs in the preview. Only a question mark inside a square or in a diamond is displayed.
This happens in all versions of Suitcase Fusion 8 on MacOS and Windows Operating Systems.
If a font is missing a single glyph used in the preview string (for example the letter ‘A’), earlier versions of Suitcase Fusion (version 7 and prior) used a substituted preview and render the font in the system font. This was to work around an issue in SF7 (and earlier versions of Suitcase) where if a single glyph was missing we wouldn’t display a preview string at all.
In Suitcase Fusion 8, we do the exact same thing Font Book or the Font Control Panel does when displaying a preview string with a missing glyph. On Mac and Windows we will display the preview but use the missing glyph character (or a Question Mark in a square on Mac and a Question Mark in a diamond on Windows) for any glyph that isn’t available in the font.
This is most common in fonts that are rendered as Glyphs such as Wingdings. These fonts remove the A-Z character strings and only display the Glyph set of the font. Therefore Suitcase will show a in place of the missing character. Or, another example of this can be seen below:
This change in Suitcase Fusion was to make sure people were seeing an accurate preview of the fonts they were viewing instead of replacing the preview string with something that might not even be rendered in the font they have selected.
Anyone seeing these examples should use the glyph viewer (click the ‘i’ next to the font name)…
… for any font they have selected to verify which glyphs the font supports.
