Price: \$12\.99 \(was \$15\.00\) \[50% off\]\?

A period inside a regex pattern doesn't mean a literal period, it means match any single character, so searching for the exact string "file.txt" with an unescaped pattern would also match "fileXtxt", a subtle bug that shows up specifically when a regex gets built dynamically from a variable string, a filename, a price, a URL, rather than typed by hand with the special characters already accounted for. This tool escapes every regex metacharacter in a string, turning it into a pattern that matches only the literal text rather than anything a stray period, asterisk, or parenthesis would otherwise mean.

Useful for safely inserting a user-supplied filename into a larger regex pattern, searching for a literal price string like "$19.99" without the dollar sign or period being misread as regex syntax, or building a dynamic pattern from a variable without a stray character silently changing what it matches.
