No Break word problem with UTF invisible characters

[ashf]

These invisible characters become a No Break word with the character right before.
But it shouldn't be in Japanese.

U+2002, U+2003, U+2004, U+2005, U+2006, U+2007, U+2008, U+2009, U+200A, U+200B

These characters (except 200B) are non-breaking by design. Unicode doesn't require that they all be non-breaking but Affinity matches the behaviour of InDesign in this regard. Does ID treat them differently with the CJK composer?

If you want a breaking space of one of these sizes in Affinity, insert a zero-width space (U+200B) before a non-breaking space. I know it's not as convenient but it's the easiest workaround.

Good luck.

Yes, ID does. It's fully compliant to CJK typography rules.
I know they are no-break in Latin.
But they must be breakable in East Asian.

I think those invisible characters including normal spaces like " " or "　"(U+3000) should be zero width at the start and the end of the line.
Adobe AI/ID and MS Word do so.
So they don't need be breakable in most cases.
Or no-break by default and an option to make them breakable manually would be nice.

Using U+200B like Mike suggested could be be a workaround but neighboring invisible characters have the width at the start and the end of the line.
