Re 1): Agree, I think it's fine to disallow newlines and maybe tabs. Anything
that would not typically be supported in filesystems either. I think the
importance of this issue is for these special spaces that seem common in CJK
languages in normal names and sentences.
Re 2): Doesn't these persistence layers need an escaping anyway? How big is the
chance they support the same broad character set?

> Support space chars common in CJK inside node names

> Key: OAK-4857
> URL: https://issues.apache.org/jira/browse/OAK-4857
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.4.7, 1.5.10
> Reporter: Alexander Klimetschek
> Attachments: OAK-4857-tests.patch
>
>
> Oak (like Jackrabbit) does not allow spaces commonly used in CJK like
> {{u3000}} (ideographic space) or {{u00A0}} (no-break space) _inside_ a node
> name, while allowing some of them (the non breaking spaces) at the _beginning
> or end_.
> They should be supported for better globalization readiness, and filesystems
> allow them, making common filesystem to JCR mappings unnecessarily hard.
> Escaping would be an option for applications, but there is currently no
> utility method for it
> ([Text.escapeIllegalJcrChars|https://jackrabbit.apache.org/api/2.8/org/apache/jackrabbit/util/Text.html#escapeIllegalJcrChars(java.lang.String)]
> will not escape these spaces), nor is it documented for applications how to
> do so.
