<div>
I'm surprised it works in .Net
</div>


<div>
I think this should work:<br />

<pre><code id="code-20-42992362-1"> (?&lt;=&gt;[^&lt;]*?\W)ă</code></pre>
<br />
\W is a non-word (non-letter, non-number) character.
</div>


I think this should work:


 (?<=>[^<]*?\W)ă


\W is a non-word (non-letter, non-number) character.

<div>
\W is a non-word, but an ASCII construct n JavaScript. It matches non-ASCII letters as well, even with the u flag. So it won't do.

<div>
<div class="content wysiwyg-content">
In .Net the regex <u>(?&lt;=&gt;[^&lt;]*?)\bă</u> works as expected (find words that start with <u>ă</u> and are not located within a tag).<br />
<br />
But in JavaScript Chrome <u>\b</u> won't work with Unicode texts.<br />
<br />
What would be the correct equivalent in JavaScript for the above .Net expression?<br />
<br />
(I am referring to the latest versions of regex/regexp)

Convert regex to regexp

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

Chrome is a free web browser created by Google. Originally released in 2008, it has grown to become the most used desktop web browser (as of October 2016).

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
