You should have felt the difficulty of adding a special character in your project at least once, except if you don’t know how to add it using unicode and CSS.
For example, characters commonly used in the mathematical field or in languages such as French, Spanish are difficult to find and to add in our projects.
That is why NoTengoEnie has attracted attention, a simple website with large collection of special characters, which we can copy and paste in our projects.
On the desktop version of website you need to enable flash to copy the special characters. If you don’t want to enable flash on your browser, you can still click on mobile button and copy the special character you want.
The only thing I didn’t like about this website is, I did not find Indian rupee symbol on this website. May be you should inform them to add this symbol in future.
