Feature #12419: Improve String#dump for Unicode output (from "\u{130}" to "\u0130")

• Status: Closed

[duerst (Martin Dürst)]

Currently, "İİİ".dump produces "\u{130}\u{130}\u{130}".

This is rather suboptimal, "\u0130\u0130\u0130" is shorter and easier to read.

The only time \u{} notation should be used is when more than four hex digits are needed.

[matz (Yukihiro Matsumoto)]

Agreed.
