Can anyone tell me what this font is or which is similar?
I'm really sorry I'm unable to provide more letters due "technical issues" and, as I've read in similar topics, answering anticipatedly, yes, I've cleaned the image, as best as I could (as I'm not a designer), as well as I've tried to identify by myself in WhatTheFont, FontSquirrel and "manually" in IdentiFont
Closest I've got was Arial, but although very similar in some letters, some didn't match.
