I ran into a problem with python where a file I wanted to read in and parse contained unexpected non-UTF-8 encoded characters. I am certain there are many ways to solve this problem, but capturing my quick and dirty appraoch below for posterity.

1. Open the file and the Open Find
2. In find, copy/paste the regex below:

^([\x00-\x7F]|[\xC2-\xDF][\x80-\xBF]|\xE0[\xA0-\xBF][\x80-\xBF]|[\xE1-\xEC][\x80-\xBF]{2}|\xED[\x80-\x9F][\x80-\xBF]|[\xEE-\xEF][\x80-\xBF]{2}|\xF0[\x90-\xBF][\x80-\xBF]{2}|[\xF1-\xF3][\x80-\xBF]{3}|\xF4[\x80-\x8F][\x80-\xBF]{2})*$

3. VS Code will highlight the lines MATCHING UTF encoded characters. So, you just have to skim the file looking for lines without highlighting.

Install Android apps or apk files in Windows using Windows Subsystem for Android

WSA or Windows Subsystem for Android is a Tool that allows Windows to run Android Apps directly without using any emulator. The problem is Windows Subsystem for Android is currently only available through preview via the Beta Channel of the Windows Insider Program. But if you follow my guide, you don't have to be in Windows Insider Program to try it out. The only thing you need is Windows 11 installed and some patience.

Prerequisites:

• Windows Subsystem for Android or WSA must be Installed.

Click here to view the guide that shows how to install Windows Subsystem for Android in any Edition of Windows 11 (including Windows 11 Home) non Inider or stable release.

How to Install Android Apps or apk files in Windows Subsystem for Android:

• First install Windows Subsystem for Android. [Click here](https://gist.github.com/HimDek/eb8704e2da1d98240153165743

PowerShell Import-Module with .ps1 quirk

Well, not so much a quirk - but an interesting anti-pattern I found in some (poor quality) PowerShell. Documenting the "how and why" so I can refer to it again if needed!

• Example
• Running
• In conclusion

Example

We have two files callme.ps1 and functions.ps1:

functions.ps1:

// 搭配 Quokka.js 來測試會比較方便看

function* rangeGenerator(start, end) {
    for (let i = start; i < end; i++) yield i;
}

function range(start, end) {
    return Array.from({ length: end - start }, (_, i) => i + start);
}
