The Nineteenth Byte

@Mego I know that. And you know that. And everyone else here in the IT department knows that. But the internal auditors don't and insist on using this third-party solution.

I hate caching.

@TimmyD But... Why?

Rainbolt

I think we used SecureDoc at the university I worked at. It was a mandate from the mother campus.

TimmyD

@Katenkyo /shrug.

Rainbolt

And our solution was brilliant: actually go to each computer in every room and install SecureDoc manually. For thousands of machines.

@EᴀsᴛᴇʀʟʏIʀᴋ That's a lotta bytes.

@El'endiaStarman Awesome.

El'endia Starman

By the way, I opened the text file in Python and it is indeed 7 bytes.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@TimmyD yes

@EᴀsᴛᴇʀʟʏIʀᴋ Is the link to Dyalog messing up the scoring?

maybe

Rainbolt

#[Dyalog APL](goo.gl/9KrKoM), 11 [bytes](meta.codegolf.stackexchange.com/a/9411/43319)

I can't print it either using either of the byte strings here.

Can't even read in the text file I created earlier and print its contents.

Anything I try returns this error: UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 1-1: Non-BMP character not supported in Tk.

I wonder if Win8 is doing some weird double-encoding thing

TimmyD

@Mego Can you run my UTF-8 code on your Windows 10 box and see if you get 3,3 or 4 for the 𩸽 character?

El'endia Starman

@Mego Well, I'm on Win10, and so are you, but we get different results, whereas TimmyD is on Win8.1 and gets the same result as I do.

Seems to be a version-independent issue.

Q: Fast way of suming up polynoms

You probably will think that this question is more about algorithms, but actually i'am searching for right formula. What i want to do is to compute $(A^n + A^{n-1} + .. + A + 1))$ mod $(10^9 + 7)$ fast. Fast is $log(n)$. $1 <= n <= 10^{18}$ $1 <= A <= 10^9$ What i have tried: Geometric...

This is a computer-science related question

on Math.SE

El'endia Starman

@Mego When I try to copy-paste it, I just get two boxes with question marks in them (regardless of code page). That said, I put it into a text file from the command line and got the original character. What the heck is going on?! o.O

Leaky Nun

so is anyone interested?

@El'endiaStarman PowerShell may have a bug with inputting non-BMP characters as well

El'endia Starman

@Mego But TimmyD doesn't seem to have a problem with it?

Anonymous

3:39 PM

Does PowerShell have a Unicode literal syntax?

TimmyD

@El'endiaStarman That could be because the font selected in your console doesn't support that character

Anonymous

Like Python's \uXXXX?

El'endia Starman

@TimmyD Oh, lemme check.

@Mego Yeah. [char]0x0000

@El'endiaStarman Only a limited subset of.

Most of the limited subset only includes letters.

I know it supports Unicode, because I have a Cygwin terminal open, also using that font

TimmyD

or [regex]::Unescape()

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@El'endiaStarman no, but i think inconsolata does

El'endia Starman

@Mego Switched to that and now it's two boxes without question marks. =_=

TimmyD

@Mego What's the Unicode literal for the character in question?

Anonymous

@TimmyD That doesn't work for wide chars like \u29e3d

TimmyD

Oh, interesting.

El'endia Starman

@EᴀsᴛᴇʀʟʏIʀᴋ I dunno how I'd get that; it's not (currently) available in the font choices.

Anonymous

Does PS have a unichr function or similar?

TimmyD

3:44 PM

@Mego For wide characters, you need [char]::ConvertFromUtf32(0x29e3d)

And that gives me the two blocks

@Mego To be fair, Unicode seems to be pretty hard for everyone. Like time zones.

Anonymous

@El'endiaStarman Yeah, but at least other devs try to support it. Microsoft seems to be adamantly opposed to sane Unicode support in PS.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

3:47 PM

@El'endiaStarman open source, try google

Anonymous

There are 2 important rules for sane Unicode support in a programming language:

Anonymous

1. Devs should not have to think about how many bytes are needed to represent the character unless they are specifically dealing with encoding and decoding.

Anonymous

2. There should be no distinction within the language between ASCII characters/strings, single-byte-encoding characters/strings, and Unicode characters/strings. One way to do that is just to make everything Unicode.

El'endia Starman

@EᴀsᴛᴇʀʟʏIʀᴋ The problem is more that there's no obvious way to add fonts to the choices I have in the command line properties dialog. I could probably figure it out with Google, but at this point, I don't care quite enough to do so. :P

Anonymous

Python 2's Unicode support was bad because it broke rule #2 - there was a strong distinction between a string (str) and a Unicode string (unicode), and everything was a str by default.

I use Cygwin frequently, but ~90% of my usage nowadays is ssh server (for my Linux server in the other room that doesn't have a monitor, mouse, or keyboard hooked up)

TimmyD

3:55 PM

@Mego Yeah, there's something really broken somewhere in the conversion here. I suspect it's the implicit cast-to-char that's anticipating a non-wide literal

Anonymous

@TimmyD The "something really broken" is just after the copyright symbol
