How isotopp became the online handle of Kristian Köhntopp

Posted by jpluimers on 2022/06/09

Like me, [Archive.is] Kristian Köhntopp is a nerd.

Unlike me, Kris bumped into character encoding issues for just about all his digital life. That started about the same time as mine, but again unlike me: he was way more involved in the technical aspects of it.

First a series of Tweets:

DELPHI : EEncodingError – Invalid code page on windows xp embedded – Stack Overflow

Posted by jpluimers on 2022/02/15

From my Windows XP days  (which are long gone), but historically relevant the answer to [Wayback] DELPHI : EEncodingError – Invalid code page on windows xp embedded – Stack Overflow by [Wayback] Remy Lebeau:

The TEncoding.ASCII property uses codepage 20127, which is not installed on XP Embedded by default. You have to install it manually. The TEncoding class does not exist in D2006.

Are you using Indy 10, by chance? It uses TEncoding.ASCII by default for its string encodings. This exact error has been known to occur when using Indy on XP Embedded.

C# Effective way to find any file’s Encoding – Stack Overflow

Posted by jpluimers on 2022/02/09

Note: notepad cannot correctly guess the encoding, see the “old new thing”: [Wayback] Some files come up strange in Notepad | The Old New Thing (talking about ANSI a.k.a. Windows-1252, UTF-16LE, UTF-16BE, UTF-8, UTF-7 somewith and some without BOM as Notepad does not understand all permutations)

David Cumps discovered that certain text files come up strange in Notepad. The reason is that Notepad has to edit files in a variety of encodings, and when its back against the wall, sometimes it’s forced to guess.

[Wayback] C# Effective way to find any file’s Encoding – Stack Overflow shows how to detect various byte order marks in C#.

(mostly ASCII) List of emoticons – Wikipedia

Posted by jpluimers on 2021/03/17

Most searches for “ASCII emoticons” get you Unicode ones:

Luckily most are ASCII in List of emoticons – Wikipedia.

There are also shortcodes, which do not visually represent an emoji, but usually get translated to the image or Unicode character.

A few lists on them:

Long read about Unicode: You, Me And The Emoji: Character Sets, Encoding And Emoji – Smashing Magazine

Posted by jpluimers on 2017/11/07

A well worth long rad:

We all recognize emoji. They’ve become the global pop stars of digital communication. But what are they, technically speaking? And what might we learn by taking a closer look at these images, characters, pictographs… whatever they are 🤔 (Thinking Face). We will dig deep to learn about how these thingamajigs work. Please note: Depending on your browser, you may not be able to see all emoji featured in this article (especially the Tifinagh characters). Also, different platforms vary in how they display emoji as well. That’s why the article always provides textual alternatives. Don’t let it discourage you from reading though! Now, let’s start with a seemingly simple question. What are emoji?
