The Unicode standard states that if you *intend* to show it in isolation, you should make it follow a space. As usual in cases where the standard talks about things like that, the intent is to settle what series of characters should be in the data to realize a given intent (or content). The question of how to display it precisely is, like all questions of rendering, outside the scope of the Standard. These two aspects are related but subtly different. Content of a text is related to archetypical appearance, not to specific realization. As rendering a non-spacing mark on a dotted circle when it appears in isolation is a quite reasonable realization of the archetype (isolated mark) it seems conformant. However, I would expect the software to not display the preceding space character in that instance. A./
