Import-CSV / Export-CSV with special characters / Bug?

Is there a way to make import/export-csv work with special characters? Try this:

cd $home
md öttö
dir | select-object Name | export-csv test.csv
import-csv test.csv

All special characters appear as "?".  


  • Hi Tobias,

    I have try this on german Windows Vista and it worked with german "Umlauten"

    dir | select-object Name | export-csv test.csv -Encoding unicode
    import-csv test.csv


    Best regards

  • Thanks, that's it. You can control Unicode encoding when you use Export-CSV. The problem occured with csv files in ANSI format generated by Excel. They show special characters correctly but when you import them via Import-CSV, special characters change.

    I still do not understand why special characters show correctly in ANSI csv files but get corrupted once imported via Import-CSV. The workaround seems to indeed be to make sure they are stored as unicode.



  • Great find! And perhaps for future reference, for Excel CSV files the workaround is to open up the .csv file in notepad and save it as unicode.

  • Hi to all,

    thank you very much for this information.

    Does someone know, which Charset Name (UTF-8, -16, ...) or ISO import-csv using?

  • -Encoding<String>

    Specifies the type of character encoding that was used in the CSV file. Valid values are Unicode, UTF7, UTF8, ASCII, UTF32, BigEndianUnicode, Default, and OEM. The default is ASCII.

  • I've solved my problem..

    Set the "-Encoding UTF8" parameter on the import and export sideBig Smile:

    (Get-Content -Encoding UTF8 C:\Temp\ads.txt) | % {$_ -replace '"', ""} | out-file -Encoding UTF8 -FilePath C:\temp\ads_UTF8.csv -Force

  • Good, 

    next time please create new thread with appropriate name instead of adding to one that is solved (no marking of solved threads is here so follow your intuition).

    In the new thread you can of course include link to any thread you want.
