digitalmars.D.bugs - [Issue 23457] New: std.string.wrap has no policy on how it counts


          Issue ID: 23457
           Summary: std.string.wrap has no policy on how it counts columns
           Product: D
           Version: D2
          Hardware: All
                OS: All

There's no hint in documentation of `std.string.wrap` whether it counts the
columns by code unit or by code point. Moreover, the function does not even
settle on one or the other. Example:

// €€ €€
// €€
wrap("€€ €€ €€", 18).writeln;
// €€ €€ €€
wrap("€€ €€", 18, "€€ ").writeln;

These both should print the same result. While either result will do, I'm
inclined to think the result should be the one with all '€':s in the same
The purpose of the function is to fit characters in a certain space, and
characters take the same amount of space regardless of encoding.
