Thank you for showing us your beautiful colour fonts. However, these do not contain filled/coloured spaces and therein lies the problem. Here are screenshots to better explain the problem:
Adobe InDesign uses spaces that you wouldn’t otherwise see to represent tabs and ligatures. This is a bug. Because in QuarkXPress or Apple Pages the character set works.
Also, I can’t even install the character set “AColorProblem.otf” under Windows. I immediately get the error message that the font does not comply with the standards.
Therefore, I have freed my font “TimeSaver Marker” (now in version 1.4) from the spaces again and can write a filled space between the letters with the key “_” (underscore). This works in InDesign and Windows. See Color font »TimeSaver Marker«
For testing here are the .AI-File and the .OTF shown in the first screenshot: Archiv.zip (353.0 KB)
