"Apple® iPad® 2 with Wi-Fi - 16GB"

"Rocketfish™ - Premium Vehicle Charger for Apple® iPad™, iPhone® and iPod®"

I need to remove special UTF8 chars such as ® ™, how can I achieve this ?

• 1 Are you sure that you can't work with those characters? Anyway, what you're looking for isn't a regex but a simple char by char filter. Way faster and way more efficient. – Colin Hebert Commented Apr 13, 2012 at 15:40

if you want to remove all symbols except basic latin just apply a regular expression like

str = str.replace(/[\u0080-\uFFFF]+/g, "");

See this list of unicode characters to choose which characters you need to accept or not

First, please make sure you absolutely cannot work with those "problematic" symbols. Clean modern program should correctly understand input in any language.

As for your request to remove anything unreadable, it is better to specify what you want to leave instead, since F. Calderan's example won't remove any extra Unicode symbols above specified FFFF position. So, considering you only want ASCII:

str = str.replace(/[^\u0000-\u007F]+/g, "");
