You have been warned!Easily convert/clean Powershell UTF-16 output to UTF-8 on Mac/Linux Here are the solutions what I found: 1. This looks like a bunch of junk when I view it in terminal on my Mac, and also it is not easily grep’able, or less/more’able. The command you are looking for is Set-Content. UTF8 and UTF16 are two different encodings. Easily convert/clean Powershell UTF-16 output to UTF-8 on Mac/Linux by jk-47 on July 18, 2012 in Linux , OSX , Powershell , TIPS I work with Powershell quite often. You have an ANSI-encoded file, or a file encoded using some other (supported) encoding, and want to convert it to UTF-8 (or another supported encoding). Why? ... Linux UX sync agrees that "doing the right thing" means making sure that PowerShell's default behavior works best with the tooling and ecosystem where it exists. Here I use the cmdlet Get-Content to get the content of the current problematic file (norwegian-vowels.txt), pipe it to Set-Content with the parameter -Encoding utf8 and a new file name as the output file (norwegian-vowels-utf8.txt). I make healthcheck systems for apps such as NetBackup, and others. after being processed by Import-Csv. To simulate the situation, I open notepad and manually enter some data causing issues. I am incredibly opinionated. A hack to list the supported encodings is to use one that doesn't exist: Type "Get-Help Set-Content -Full" at a PowerShell prompt to read the help text, and see the example below. With this tool you can easily convert UTF16-encoded text to UTF8-encoded text. Well thats how the terminal converts the unicode.Typically in Powershell, you can issue this command, and force the Unicode output to be ascii:The problem is, it doesn’t always work. I ran into this when working with exported data from Excel which was in latin1/ISO8859-1 by default, and I couldn't find a way to specify UTF-8 in Excel. With this tool you can easily convert UTF8 data to UTF16 data. Personally I would use UTF-8, because most of the applications I write have to communicate with Linux applications or some form of http so UTF-8 is more likely. In my case I was trying to debug malformed UTF8 characters. Besides even if all your code is used with Microsoft systems it's easy to convert to UTF-8 and a simple substitute regular expression could change everything over to Unicode (UTF-16) if .NET started requiring it. You can change any of the charactersets as your destination.My posts are my own opinion and experiences, and do not reflect the opinions of my employer, my ex-dog, my ex-wife, or anyone else. The data contains the "extra" Norwegian vowels "æ", "ø" and "å", and their position in the Norwegian alphabet in a manually crafted CSV file. It's implemented directly using the .NET System.String type, which is a reference type (read more about that in my A string can be arbitrarily long (computer memory and physics as we currently understand it allowing) and it is immutable, meaning it can't be changed without creating an entirely new altered version/"copy" of the string. UTF8 uses a variable length encoding scheme that encodes each Unicode code point using one to four bytes but UTF16 is fixed at two or four bytes. Internally in PowerShell, a string is a sequence of 16-bit Unicode characters (often called a Unicode code point or Unicode scalar value).
Here you see the Norwegian vowels are incorrectly displayed as question marks ("?") Listing the cmdlet Set-Content's Supported EncodingsAdditional Information and Avoiding a Temporary FileListing the cmdlet Set-Content's Supported EncodingsAdditional Information and Avoiding a Temporary File This is the best question I search that lead me to the above solution for text encoding/decoding characters in PowerShell.
“sudo port install iconv”After that, you can simply process ALL files or just one file at a time to output it to a new file in the right text encoding.It’s just that easy.
What I've tried: Passing the command to run via the -Command parameter; Writing the PowerShell script as a file to disk with UTF-8 … Hope it helps someone in the future.-Check that BOM At the moment it supports UTF16 input in hex format but soon it will be able to detect all bases. UTF-16 to UTF8. 1 command. I haven’t looked too far into the WHY of it not working, but it’s a big ol pain in the ass and when I need it to, it doesn’t.Cleaning up this text is INCREDIBLY easy! It works with both little-endian and big-endian UTF16 input. The data is in SQL 2005 and is stored in UTF-16, but my recipient doesn't accept utf-16, only utf-8.
I'm trying to use Process.Start with redirected I/O to call PowerShell.exe with a string, and to get the output back, all in UTF-8.But I don't seem to be able to make this work.
I work with Powershell quite often. It looks I solved the problem, just I'm not sure that the result is utf-8. That’s it. no, I need utf-8 at the end. Convert to UTF-8 and Verify It Displays Correctly. The problem occurred when I wanted to work on the CSV file using the PowerShell cmdlet Import-Csv, which, as far as I can tell, doesn't work correctly with latin1-encoded files exported from Excel or ANSI files created with notepad - if they contain non-US characters. Notepad has some logic that determines what file encoding it uses, but the default is ANSI, and that is what it uses in this example.
