I know both of them have the same font, but what's her name? Please.

Thanks to both of you, I'll use Grover and manip the 'E'

You're welcome... The character '∑' is already pretty close to the 'E'...

I tested it, and I don't know why it wasn't green in other threads.

Yep, I have a fan page for her and there is definitely something wrong with the "E" and "F". I suggest just using another font for the "E" that looks similar to hers. For example; the font "Code Bold" works for me.
