So clean code... Thank you Paul.

I think so too, here's the proof: ```d import std.string, std.stdio; void main() { auto istanbul = "\u0131stanbul"; enum capitalized = "Istanbul"; assert(istanbul.capitalize == capitalized); assert("istanbul".capitalize == capitalized); } ``` Different characters but same and seamless results...

Which it probably shouldn't be as there is an actual character for that. We might need to update our unicode database... or something. It's not the wrong lower-case character. Turkish uses U+0069 (a.k.a. ASCII 'i') for lower-case dotted I, but has a non-default case mapping that pairs U+0069 with U+0130 ('İ') rather than U+0049 (ASCII 'I'). Phobos' std.uni uses the default case mapping for its toUpper function, so it does not produce the correct result for Turkish text.
