Just a small tip for designer guys. Sometime we stuck at a very small point during our work. It was also happened to me, so here is the method of adding Trademark symbol (TM), Copyright symbol (C) and Registered symbol (R) in Adobe Photoshop or Illustrator. Just copy the character from below and paste it in Photoshop text, or hold down the alt key and use the num-pad on your keyboard to type.
copyright – 0169 – ©
registered – 0174 – ®
trademark – 0153 – ™
You can also find symbols in few fonts like, wingdings, webdings etc. They are much helpful in your design projects.
