What's this?

highlight(text, phrase, highlighter = '\1') public

Highlights the phrase where it is found in the text by surrounding it like <strong class="highlight">I’m a highlight phrase</strong>. The highlighter can be specialized by passing highlighter as single-quoted string with \1 where the phrase is supposed to be inserted. N.B.: The phrase is sanitized to include only letters, digits, and spaces before use.
