(97 13)

Xliff

O_o? -- Isn't that (97 10 13)?

Xliff: no, "\r\n" is a grapheme cluster which what we usually see as a single character. The ord method however is documented as looking at the first Unicode code point in the string.

06:52

Xliff

nine: Thanks. What should I be using, instead? .grapheme?

06:54

Is there a a thing?

s/a a/such a/

nine

Depends on what you're trying to do?

06:55

moon-child

Xliff: I would guess you want codepoints

06:58

Xliff

I want a way to see "\r\n" as (10 13)

07:00

However I am well aware that what I want isn't what I need. :)

nine

Xliff: that still leaves several options, so the question remains: what do you want that for?

07:01

moon-child

m: .say for "a\r\n".NFC

moon-child

Xliff: what do you want to do about combining characters?

Xliff

moonchild++ # .NFC works!

07:04

nine

For the very limited use case you've shown

07:05

Xliff

nine: Limited for a reason, thanks.

moon-child

what do you want this for?

lizmat

m: .say for "a\r\n".encode

Great minds think alike :)

moon-child

yea but then

moon-child: exactly! That's why the other use cases matter

Xliff

D'oh! I should have thought about .encode! I was using it in this code, too!

07:35

m: "Encode\0\0\0".encode.say

07:36

camelia

utf8:0x<45 6E 63 6F 64 65 00 00 00>

Xliff

m: say "Encode\0\0\0" eq 'Encode'

camelia

False
