Answer 1

You need the parentheses that appear in the original regular expression. In regular expression notation, parentheses form a "match group" which is substituted in for the "$1" in the replace string.

$this.html($this.text().replace(/([^\x00-\x80]+)/g, "$1"));

Without any match groups in your regex, the $1 is simply treated as a literal dollar sign and one.

When you have multiple parenthesized match groups, the groups are used in to replace dollar-sign-denoted numbered placeholders in the order that the match groups are opened (the first match group replaces $1, the second replaces $2, etc).
