Hi,

a URI (https://tools.ietf.org/html/draft-ietf-netconf-restconf-16#section-5.1) can contains only chars from US-ASCII(7-bit) according to RFC3986 (https://tools.ietf.org/html/rfc3986#section-2).

Regards,

Jakub Toth

"The key value is specified as a string, using the canonical
representation for the YANG data type. Any reserved characters
MUST be percent-encoded, according to [RFC3986], section 2.1 and
2.5. The comma (',') character MUST be percent-encoded if it is
present in the key value." [0]

The percent encoding refers to octets, while Yang string definition refers to Unicode and ISO/IEC 10646. Hopefully that works out ok; if not, it is a separate Bug.
