Accepting HTML entity name in string literal
String literal allows the escape character
\u to describe a character using UTF-8 character code like this:
"\u201c" # left double quote "\u2191" # up arrow
This is useful in typing characters that are not easy to input from the keyboard. However, normal people do not memorize the UTF-8 codes by heart.
The HTML symbol entity name is the place where we can compromise (although it is not available for the entire UTF-8), I think. I would like the string literal to be extended to accept HTML entity names and interpret them as the corresponding UTF-8 characters. I do not have a definite idea for the syntax, but a candidate can be an escape character
\& ... ;, so that we can type:
"\“" # left double quote "\↑" # up arrow
"\&" is interpreted as
"&", so this will be a compatibility breaking change, and if that is not desirable, perhaps a different syntax may be considered.
