I confirmed that the definition of ns-tag-char was changed
from YAML 1.1 to YAML 1.2. What I showed was from YAML 1.2. 
The ns-tag-char in YAML 1.1 indeed did not include "#" in 
its definition. I had not checked for it.

[112] c-ns-shorthand-tag ::= ( c-primary-tag-handle  ns-tag-char+ )
                           | ( ns-secondary-tag-handle ns-uri-char+ )
                           | ( c-named-tag-handle ns-uri-char+ ) 

[44] ns-tag-char ::= ns-uri-char - “!”

[43] ns-uri-char ::= ns-word-char  | “%” ns-hex-digit  ns-hex-digit
          | “;” | “/” | “?” | “:” | “@” | “&” | “=” | “+” | “$” | “,”
          | “_” | “.” | “!” | “~” | “*” | “'” | “(” | “)” | “[” | “]” 

I think this was kind of a bug in the YAML specification because 
it, on the other hand, described tags that contain "#" characters 
in Sect. 3.2.1.2. With the old specification, we can specify such 
Tags only with the URI escape sequence.
