<div class="content wysiwyg-content">
I have a file with some binary characters that are unrecognizable in any of my text editors. <br />
<br />
For example, I would see something like this:<br />
<br />
\xC2Freien - with \xC2 being some binary character. I attempted to make this substitution in my processing script to clean these out:<br />
<br />
s/[^[:ascii:]]Freien/Freie<wbr />n/g;<br />
<br />
However, it failed to do so. I know I can do something like this:<br />
<br />
s/[^[:ascii:]]//g;<br />
<br />
While this will get rid of those binary characters, it will also strip out non-ASCII characters I do what to keep. <br />
<br />
I know I can also do hexadecimal substitution like this:<br />
<br />
s/\xC2Freien/Freien/g;<br />
<br />
However, in future cases I won't always know the hexadecimal value.<br />
<br />
I can't cut &amp;&nbsp;paste binary characters like this because \xC2 will transform into this: ? in the cut &amp;&nbsp;paste process

Substitutions involving non-ASCII characters

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.

Perl

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.
