The "points" are called "body" in the Czech langauge., the short version is "b". Unfortunately Adobe CC apps are very inconsistent and you can find "b" (InDesign, Photoshop), "b." (InDesign) or even not translated "pt" (Illustrator).

Please make it consistent. If you can't change it in all Adobe apps, at least make it "b" in InDesign. (Adobe CS 6 is correct, line thickness is represented as "b" while CC displays "b.".
