How can I change a huge text file from ANSI to UTF-8?

I have a text file whose size is 1.3 GB. Most of text editors (including NotePad++) cannot open it. I need to change its format from ANSI to UTF-8. In what program can I do this?

If you want a free (and open source) command-line tool that can run on Windows, and which allows you to convert huge files from ANSI to UTF-8 (or any other encodings), you can use this tool that I've just created (runs on nodejs and uses the iconv-lite library):

https://github.com/sorin-postelnicu/convert-file-encoding

You can use it like this:

node bin\convertFileEncoding.js -f latin-1 -t utf-8 -i myinputfile.txt -o myoutputfile.txt

It is fast and supports converting very large files with minimal memory consumption (around 20MB of RAM no matter the size of the input file).

You can also use shareware text editor UltraEdit.

First, configure UltraEdit for editing large files according to power tip large file text editor.

Then open your file in UltraEdit and use File - Save As and select for Encoding (Windows 7/8/8.1/Vista) respectively Format (Windows XP/2000) the option UTF-8 - NO BOM or UTF-8 for saving with conversion to UTF-8 encoding without or with byte order mark at beginning of the file.
