I'm trying to upload my company logo to set up campaign content. However, when I tried to upload it keeps giving me an error that I have special characters in my image. I have uploaded my company's logo to many different websites but I have never encountered this problem before. Why does it matter that my image has special characters and furthermore in my company logo? It is not as if I'm using some controversial images.

Does this mean I can never use Zoho at all since I cannot even use my company logo? I cannot even upload my company logo for this post. What's going on here?
