"fix" tag on feature text class removes space glyph when spell fixing

3236 version

sorry, the order of the screenshots should be reversed

This only happens when I export an older FontLab file to Glyphs and open it to clean up red marked errors in “info” view

Ah, it seems to remove the space. Can you check if the space is a normal space (Unicode U+0020) or some other whitespace character? Best to copy and paste the text in UnicodeChecker’s tool box (Cmd-2, then pick the Split Up function).

looks like a plain space.
