script to save file as unicode

Question

Do you know any way that I could programmatically or via scrirpt transform a set of text files saved in ansi character encoding, to unicode encoding?

I would like to do the same as I do when I open the file with notepad and choose to save it as an unicode file.

Answer 1

This could work for you, but notice that it'll grab every file in the current folder:

Get-ChildItem | Foreach-Object { $c = (Get-Content $_); `
Set-Content -Encoding UTF8 $c -Path ($_.name + "u") }

Same thing using aliases for brevity:

gci | %{ $c = (gc $_); sc -Encoding UTF8 $c -Path ($_.name + "u") }

Steven Murawski suggests using Out-File instead. The differences between both cmdlets are the following:

• Out-File will attempt to format the input it receives.
• Out-File's default encoding is Unicode-based, whereas Set-Content uses the system's default.

Here's an example assuming the file test.txt doesn't exist in either case:

PS> [system.string] | Out-File test.txt
PS> Get-Content test.txt

IsPublic IsSerial Name                                     BaseType          
-------- -------- ----                                     --------          
True     True     String                                   System.Object     

# test.txt encoding is Unicode-based with BOM

PS> [system.string] | Set-Content test.txt
PS> Get-Content test.txt

System.String

# test.txt encoding is "ANSI" (Windows character set)

In fact, if you don't need any specific Unicode encoding, you could as well do the following to convert a text file to Unicode:

PS> Get-Content sourceASCII.txt > targetUnicode.txt

Out-File is a "redirection operator with optional parameters" of sorts.

Answer 2

The easiest way would be Get-Content 'path/to/text/file' | out-file 'name/of/file'.

Out-File has an -encoding parameter, the default of which is Unicode.

If you wanted to script a batch of them, you could do something like

$files = get-childitem 'directory/of/text/files' 
foreach ($file in $files) 
{
  get-content $file | out-file $file.fullname
}

Answer 3

Use the System.IO.StreamReader(To read the file contents) class together with the System.Text.Encoding.Encoding(To create the Encoder object which does the encoding) base class.

Answer 4

You could create a new text file and write the bytes from the original file into the new one, placing a '\0' before each original byte (assuming the original text file was in English).

Answer 5

pseudo code...

Dim system, file, contents, newFile, oldFile

Const ForReading = 1, ForWriting = 2, ForAppending = 3 Const AnsiFile = -2, UnicodeFile = -1

Set system = CreateObject("Scripting.FileSystemObject...

Set file = system.GetFile("text1.txt")

Set oldFile = file.OpenAsTextStream(ForReading, AnsiFile)

contents = oldFile.ReadAll()

oldFile.Close

system.CreateTextFile "text1.txt"

Set file = system.GetFile("text1.txt")

Set newFile = file.OpenAsTextStream(ForWriting, UnicodeFile)

newFile.Write contents

newFile.Close

Hope this approach will work..

Answer 6

You can use iconv. On Windows you can use it under Cygwin.

iconv -f from_encoding -t to_encoding file
