For the moment, if you are using Microsoft Windows XP, try this method :
1. Start>Programs>Accessories>System Tools>Character Map
2. From the chosen font type, locate the character ©
3. Click "SELECT" and then "COPY" to transfer character to clipboard
4. Goto Photoshop and paste accordingly.
I would like to thank you all for the suggestions and contributions.
I got the solution and also learned something by this.
As mentioned by Andy Ang the Ascii code works only when the numbers input comes from from the Number Pad Keys. :thumbsup:
In other words attempting to get the symbol by using the code ALT+169 on the laptop it doesn't work, but by using an esternal keybord it's succesfull.
Make sure you are using your keypad 0169 and not the 0169 on your main keyboard. If you are using a notebook without the keypad, you must use the numlock and use the virtual keypad within the main keyboard.
