I'm using InDesign CS6 and the font is correct in both os.
When I insert the character from glyph, I've no issues in windows & mac.
But when I'm inserting alpha not from glyph, InDesign preflight should throw error 'glyph missing'. This happens only in mac not in windows. I think it is related to glyph not to font. Am I correct? I should get 'glyph missing' in windows also, why windows InDesign is not indicating as mac?
