How to have a leaf named : leaf-#

hello,

I’m looking for name a leaf with an hash ‘#’
is it possible to name a leaf with the name “leaf-#” ?
when i name my leaf i got an error.
exemple

leaf leaf-#
{
type empty;
tailf:cli-optional-in-sequence;
tailf:info “help”;
}

hello,

i believe this is not possible - YANG defines leaf name as (excerpt from RFC 7950):

identifier          = (ALPHA / "_")
                         *(ALPHA / DIGIT / "_" / "-" / ".")

so, you can use only letters/numbers and the few “extras” - underscore, dash, dot.
