Re: Dotted Circle plus Combining Mark as Text

Is there standard way in Unicode to specify tht one wants to display a combining mark in isolation ? Which leading charcter should be used (that should not display by itself but would force the separation from the previaous context) which can also act as valid leader in combining sequences, and wo

Re: Dotted Circle plus Combining Mark as Text

I suspect it is a font issue, rather than a renderer issue, but then using a dotted circle is a convention used in the unicode charts and in the unicode spec. It is not a combination I'd expect a font developer from SE Asia to necessarily support. Since publications in SE Asia have their own typog

Re: Dotted Circle plus Combining Mark as Text

This could be enforced in OpenType by making this mapping of U+25CC within a dedicated feature In fact the feature could instead map the combining marks directly to the glyph ID showing the combining mark with its suitable dotted glyph. The renderer would then lookup this feature directly for the

Re: Dotted Circle plus Combining Mark as Text

OK for ZWSP, I overlooked it because of its name. In fact I want to include all characters that have some whitespace property (to investigate), so that renderers would add them automatically in their list of suitable base characters for which theyr should NOT insert any dotted circle as the defaul
