Is there a Unicode-aware grep for Windows 32-bit?

Did you find one that worked with Unicode? It is not at all clear in the answers if the different tools are Unicode-aware or not. –  Peter Mortensen May 22 '12 at 9:26
    
I gave up and used the built-in search of Visual Studio (: –  Jeroen Wiert Pluimers May 22 '12 at 11:39

For a command line tool, look at KeyboardMonkey answer (but I'm not sure about Unicode support).

For an (open source) GUI tool: dnGREP

  • Shell integration (ability to search from Windows Explorer)
  • Plain text, regular expression, and XPath search (including case-insensitive search)
  • Phonetic search (using Bitap and Needleman-Wunch algorithms)
  • File move/copy/delete actions
  • Search inside archives / MS Word documents / PDF documents (via plug-ins)
  • Undo functionality
  • Optional integration with text editor (like Notepad++)
  • Bookmarks (ability to save regular expression searches for the future)
  • Pattern test form
  • Search result highlighting
  • Does not require installation (can be run from a USB drive)

For a more simple (only search) GUI tool: AstroGrep and for a more featured (and expensive) one: PowerGREP

According to gizmo's freeware, "Replace Text" ecobyte.com/replacetext is another interesting option –  fluxtendu Feb 9 '10 at 18:13

Most versions of Windows include the command "findstr" which works much like grep. I do not know about its Unicode abilities, but to my knowledge there shouldn't be any problems with that.

Update: GnuWin32 is a more recently maintained port of these tools. (Thanks Quack)

Here is a list of the packages and to download grep individually.

Have a look at UnxUtils, which includes grep as well. I use these on my work PC, too.

UnxUtils is old and unsupported -- last updated in 2003. try GnuWin32 for a more recent toolset: gnuwin32.sourceforge.net –  quack quixote Feb 9 '10 at 18:16
    
Thanks for the update, quack! –  invert Feb 11 '10 at 6:28

Yes, as fluxtendu mentions,

  • PowerGREP will do all that. But it is proprietary and costs 149 Euros.
  • dnGREP will work too, and has a similar feature set for free.

However,

  • Cygwin can also install grep (and a whole lot more if you want.) It will do Unicode search with the -U switch. I would recommend Cygwin as the simplest solution if you're familiar with Unix grep. Just make sure to append your PATH and you can use it in the Windows shell too.

See BareGrep (free version has a startup splash screen), which seems to be a quite complete graphical grep. The documentation mentions support for "Many file formats", so I would imagine that Unicode is included.

I'm pretty sure it does NOT support Unicode. I tried it and it doesn't work on UTF-16 files. Have emailed them to confirm. –  O'Rooney Sep 2 '13 at 0:55

I asked this question a while back and finally discovered grepWin which is a GUI via the shell context menu. Works quite well.
