A workaround is to convert your UTF-16 to ASCII or ANSI

<pre><code>TYPE UTF-16.txt &gt; ASCII.txt
</code></pre>

Then you can use FINDSTR.

<pre><code>FINDSTR object ASCII.txt
</code></pre>

Thanks for the suggestions. I was referring to Windows Vista and XP.

I also discovered this workaround, using free <a href="http://technet.microsoft.com/en-us/sysinternals/bb897439.aspx" rel="nofollow noreferrer">Sysinternals <code>strings.exe</code></a>:

<pre><code>C:\&gt; strings -s -b dir_tree_to_search | grep regexp 
</code></pre>

<code>Strings.exe</code> extracts all of the strings it finds (from binaries, but works fine with text files too) and prepends each result with a filename and colon, so take that into account in the regexp (or use cut or another step in the pipeline). The <code>-s</code> makes it do a recursive extraction and <code>-b</code> just suppresses the banner message.

Ultimately I'm still kind of surprised that the flagship searching utilities Gnu <code>grep</code> and <code>findstr</code> don't handle Unicode character encodings natively.

blocks|key|434829|text|在Windows上，您也可以使用find.exe。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|434830|find+/i+/n+"YourSearchString"+*.*|code-block|syntax|javascript|434831|唯一的问题是这个打印文件名后跟着匹配。你可以通过管道过滤到findstr。|434832|find+/i+/n+"YourSearchString"+*.*+%7C+findstr+/i+"YourSearchString"|434833|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

On Windows, you can also use find.exe. 

<pre><code>find /i /n "YourSearchString" *.*
</code></pre>

The only problem is this prints file names followed by matches. You may filter them by piping to findstr

<pre><code>find /i /n "YourSearchString" *.* | findstr /i "YourSearchString"
</code></pre>

According to this <a href="http://dcortesi.com/2008/07/16/unicode-grep/" rel="nofollow noreferrer">blog article</a> by Damon Cortesi grep doesn't work with UTF-16 files, as you found out. However, it presents this work-around:

<pre><code>for f in `find . -type f | xargs -I {} file {} | grep UTF-16 | cut -f1 -d\:`
 do iconv -f UTF-16 -t UTF-8 $f | grep -iH --label=$f ${GREP_FOR}
done
</code></pre>

This is obviously for Unix, not sure what the equivalent on Windows would be. The author of that article also provides a shell-script to do the above that you can find on github <a href="http://github.com/dacort/ugrep/tree/master" rel="nofollow noreferrer">here</a>.

This only greps files that are UTF-16. You'd also grep your ASCII files the normal way.

blocks|key|434895|text|在Windows的更高版本中，UTF-16是支持开箱即用的.如果没有，请尝试通过chcp命令更改活动代码页。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|434896|在我的例子中，单独使用findstr对UTF-16文件是失败的，但是它与type一起工作。|434897|type+*.*+%7C+findstr+/s+/c:some-symbol|code-block|syntax|javascript|434898|entityMap^0|14|4|0|B|7|10|4|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|H|3|I|5|J|7|W|8|@]|D|@]|E|$K|L]]|$1|M|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|N|$]]

In higher versions of Windows, UTF-16 is supported out-of-box. If not, try changing active code page by <code>chcp</code> command.

In my case when using <code>findstr</code> alone was failing for UTF-16 files, however it worked with <code>type</code>:

<pre><code>type *.* | findstr /s /c:some-symbol
</code></pre>

blocks|key|1968362|text|你没说你想在哪个平台上做这个。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1968363|在Windows上，您可以使用PowerGREP，它自动检测以字节顺序标记开头的Unicode文件。(在没有BOM的情况下，还可以自动检测文件。UTF-8的自动检测是非常可靠的，但对UTF-16的自动检测是有限的.|offset|length|1968364|entityMap|0|LINK|mutability|MUTABLE|url|http://www.powergrep.com/^0|0|F|9|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

You didn't say which platform you want to do this on.

On Windows, you could use <a href="http://www.powergrep.com" rel="nofollow noreferrer">PowerGREP</a>, which automatically detects Unicode files that start with a byte order mark. (There's also an option to auto-detect files without a BOM. The auto-detection is very reliable for UTF-8, but limited for UTF-16.)

I want to do this: 

<pre><code> findstr /s /c:some-symbol *
</code></pre>

or the grep equivalent

<pre><code> grep -R some-symbol *
</code></pre>

but I need the utility to autodetect files encoded in UTF-16 (and friends) and search them appropriately. My files even have the byte-ordering mark FFEE in them so I'm not even looking for heroic autodetection.

Any suggestions?

我想这么做： findstr /s /c:some-symbol *或相当于grep的 grep -R some-symbol *但我需要这个实用程序来自动检测UTF-16 (和朋友)中编码的文件，并对它们进行适当的搜索。我的文件甚至有字节排序标记FFEE在他们中，所以我甚至不寻找英雄自动检测。有什么建议吗？我指的是Windows和XP。
