https://issues.dlang.org/show_bug.cgi?id=23457 Issue ID: 23457 Summary: std.string.wrap has no policy on how it counts columns Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: Ajieskola gmail.com 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: ```D // €€ €€ // €€ // 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 line. The purpose of the function is to fit characters in a certain space, and characters take the same amount of space regardless of encoding. --
