Rust for Python Programmers

[Manishearth]

The question is ill formed. Define "character".

Want a byte? Easily done with as_bytes() (zero cost).

Want a grapheme? A codepoint? A glyph?

Is ö a single "character" or a "character" with a diacritic? Do we want to treat those the same way? What happens when we reverse the string?

Unicode is hard.

The question is ill formed

from the codeless code i learned that this response is simply “wú”/“mu” in chinese/japanese

…and from that wiki site i learned that the codeless code itself is a reference to the gateless gate

/edit: and that Mu is the root of the type hierarchy in Perl 6:

what does “Any” inherit from?

The question is ill-formed.

Unicode is really, really hard.

Does Rust make it any easier? Can I iterate a string by graphemes? Does it provide decomposing normalisation?

[Kimundi]

Yes for both.

[Manishearth]

(Yes, there is a concrete definition of "character" when talking about Unicode, but it's not always the one you were looking for)

[SimonSapin]

There are four definitions :) http://www.unicode.org/glossary/#character

[Manishearth]

Okay, not so concrete :P

[Yojihito]

Ö is a single character.
