To add to the confusion, the ECMA-334 standard writes in its reference PDF (page
27):
This clause is informative.
(...)
The name C# is pronounced "C Sharp".
The name C# is written as the LATIN CAPITAL LETTER C (U+0043) followed
by the NUMBER SIGN # (U+000D).
End of informative text.
Yes it contains an error for the Unicode code point (not U+000D as indicated),
but it states it is to we written with the "NUMBER SIGN". The "informative"
pronounciation is not mandatory, not even, the orthograph (which also contains
an error...)
