I'd expand the message with an explanation of what actually happens here. Also
it's not clear what the "to_string operation" refers to. And one more thing I
missed, is other character types.
So I'd go with something similar to: "an integer is interpreted as a character
code when assigning it to a string; if this is intended, cast the integer to
'%0'; if you want a string representation, use
%select{std::to_string()|std::to_wstring()|appropriate conversion facility}1",
where %0 should be substituted with `char`/`wchar_t`/whatever the specific
character type is.
(and please add tests for other character types)
