What is the fastest, easiest tool or method to convert text files between character sets?

Specifically, I need to convert from UTF-8 to ISO-8859-15 and vice versa.

Everything goes: one-liners in your favorite scripting language, command-line tools or other utilities for OS, web sites, etc.

Best solutions so far:

On Linux/UNIX/OS X/cygwin:

  • Gnu iconv suggested by Troels Arvin is best used as a filter. It seems to be universally available. Example:

    $ iconv -f UTF-8 -t ISO-8859-15 in.txt > out.txt
    

    As pointed out by Ben, there is an online converter using iconv.

  • Gnu recode (manual) suggested by Cheekysoft will convert one or several files in-place. Example:

    $ recode UTF8..ISO-8859-15 in.txt
    

    This one uses shorter aliases:

    $ recode utf8..l9 in.txt
    

    Recode also supports surfaces which can be used to convert between different line ending types and encodings:

    Convert newlines from LF (Unix) to CR-LF (DOS):

    $ recode ../CR-LF in.txt
    

    Base64 encode file:

    $ recode ../Base64 in.txt
    

    You can also combine them.

    Convert a Base64 encoded UTF8 file with Unix line endings to Base64 encoded Latin 1 file with Dos line endings:

    $ recode utf8/Base64..l1/CR-LF/Base64 file.txt
    

On Windows with Powershell (Jay Bazuzi):

  • PS C:\> gc -en utf8 in.txt | Out-File -en ascii out.txt

    (No ISO-8859-15 support though; it says that supported charsets are unicode, utf7, utf8, utf32, ascii, bigendianunicode, default, and oem.)

Edit

Do you mean iso-8859-1 support? Using "String" does this e.g. for vice versa

gc -en string in.txt | Out-File -en utf8 out.txt

Note: The possible enumeration values are "Unknown, String, Unicode, Byte, BigEndianUnicode, UTF8, UTF7, Ascii".


Stand-alone utility approach

iconv -f ISO-8859-1 -t UTF-8 in.txt > out.txt
-f ENCODING  the encoding of the input
-t ENCODING  the encoding of the output

You don't have to specify either of these arguments. They will default to your current locale, which is usually UTF-8.

How to Convert a File From ANSI to UTF8, How do I convert a file to UTF 8 in Unix? Use a code page conversion utility. Some run on your PC while others are available online. On linux and Unix, the standard program for this purpose is called iconv. The Windows equivalent is called win-iconv. A code page is a mapping between bit patterns and generic symbols aka glyphs. A list of code pages is available.


Try VIM

If you have vim you can use this:

Not tested for every encoding.

The cool part about this is that you don't have to know the source encoding

vim +"set nobomb | set fenc=utf8 | x" filename.txt

Be aware that this command modify directly the file


Explanation part!
  1. + : Used by vim to directly enter command when opening a file. Usualy used to open a file at a specific line: vim +14 file.txt
  2. | : Separator of multiple commands (like ; in bash)
  3. set nobomb : no utf-8 BOM
  4. set fenc=utf8 : Set new encoding to utf-8 doc link
  5. x : Save and close file
  6. filename.txt : path to the file
  7. " : qotes are here because of pipes. (otherwise bash will use them as bash pipe)

Best way to convert text files between character sets? – Website , How do I change the encoding of a file in Linux? An encoding is the set of rules with which to convert something from one representation to another. Other terms which deserve clarification in this context: character set, charset The set of characters that can be encoded. "The ASCII encoding encompasses a character set of 128 characters." Essentially synonymous to "encoding". code page


Under Linux you can use the very powerful recode command to try and convert between the different charsets as well as any line ending issues. recode -l will show you all of the formats and encodings that the tool can convert between. It is likely to be a VERY long list.

Programming, What is the fastest, easiest tool or method to convert text files between character sets? Specifically, I need to convert from UTF-8 to ISO-8859-15  A decoder converts a byte array that reflects a particular character encoding into a set of characters, either in a character array or in a string. To decode a byte array into a character array, you call the Encoding.GetChars method. To decode a byte array into a string, you call the GetString method.


iconv(1)

iconv -f FROM-ENCODING -t TO-ENCODING file.txt

Also there are iconv-based tools in many languages.

On linux and Unix, the standard program for this purpose is called  The character set becomes more important when you use database functions to compare, convert and measure the data. For example, the LENGTH of a field may depend on its character set, as do string comparisons using LIKE and =. The method used to compare strings is called a collation. Character sets and collations in MySQL are an in-depth subject.


Get-Content -Encoding UTF8 FILE-UTF8.TXT | Out-File -Encoding UTF7 FILE-UTF7.TXT

The shortest version, if you can assume that the input BOM is correct:

gc FILE.TXT | Out-File -en utf7 file-utf7.txt

How to Convert Files to UTF-8 Encoding in Linux, What is the fastest, easiest tool or method to convert text files between character sets? Specifically, I need to convert from UTF-8 to ISO-8859-15  You can use it as utf-8 because the equivalent utf-8 characters to all ASCII characters are identical (means converting an ASCII-file to an utf-8-file results in an identical file (if it gets no BOM)). For all who have non-ASCII characters in their text this answer is just false and misleading.


Choose text encoding when you open and save files, In simple terms, character encoding is a way of informing a computer There are various encoding schemes out there such as ASCII, ANSI, Unicode among others​. In Linux, the iconv command line tool is used to convert text from one TecMint is the fastest growing and most trusted community site for  UTF-8 and UTF-16 are variable length encodings. In UTF-8, a character may occupy a minimum of 8 bits. In UTF-16, a character length starts with 16 bits. UTF-32 is a fixed length encoding of 32 bits. UTF-8 uses the ASCII set for the first 128 characters. That's handy because it means ASCII text is also valid in UTF-8.


Character encodings for beginners, When you or someone else opens a text file in Microsoft Word or in another program used to create the file — the encoding standard helps that program determine how to Unicode accommodates most characters sets across all the languages that are Top of Page In the Convert File dialog box, select Encoded Text. The Unix version of the file, after all, has been stripped of its carriage returns so it's four characters smaller. $ file DarkBeers.txt DarkBeers.txt: ASCII text, with CRLF line terminators $ ls
