I would like to point out that with all due respect, how particular fonts or rendering engines behave is only marginally relevant to the Unicode list. I think that we should deal only with the Unicode specification.Point taken. But when different fonts and rendering engines give different results because the standard is unclear or ambiguous, that is a matter for the discussion here. And when conforming fonts and rendering engines fail to give the required results, that may also be because of a deficiency in the standard.
A particular implementation or many implementations may not behave as expected, and then may be either conformant or non-conformant, or may behave as expected and still be either conformant or non-conformant. Messages such as the attached help the discussion of the specification only as illustrations and as a basis for discussing conformity.

Thank you. Well, this sort of works. I looked in various fonts. In some of them the diacritic is centred in the space between the words "diacritic" and "may", but in others it is offset to the left or the right. The problem is that the space is wider than the diacritic, which confuses things, and all the more so no doubt if it expands for justification. NBSP would probably be a better choice in that it is less likely to expand. But what I am looking for is a diacritic holder which is defined to be only as wide as the diacritic. On the principle that base characters expand to fit the width of the diacritic, ZWSP or, better, a real (rather than misnamed) zero width no break space would seem to have the right properties for that.instead of ^ I want to use a combining character" and want to display exactly one space before the combining character - do I encode two spaces or one?In this language the diacritic ̊ may appear above the letters...
Two spaces, at least in Thunderbird Mail.

It seems that many rendering engines give to the sequence space, combining mark the width normally assigned to a space. Is this actually what the standard suggests? I have identified a need to display combining marks with no extra width, only the width required by the mark. Should the sequence space, combining mark do what I want, or shouldn't it? If so, this needs to be spelled out so that rendering engines know what they are supposed to do. If not, there may be a need for a new character. This is a deficiency in the standard, not in the rendering engines.
