Hello again! This is the same problem described here > [@حدوث مشكلة عند ايداع اليدوي](https://community.crossref.org/t/topic/4558/3): > > Hi, Thanks for sending the submission ID. The invalid character occurs in the title \decomposition of 2-propanol over Alumina supported Thoria and Potassium ion modified catalysts\ It’s in between “modi” and "fied’. When I open your xml in a text editor it appears as a question mark, which is a [replacement character]([Specials (Unicode block) - Wikipedia](https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character). In other contexts, you might see it as a white question mark in a black diamond, or a hollow square, or just a blank space.… In this case, the invalid character is in the abstract `This paper investigates the issue of investment in renewable energy (RE) particularly solar photovoltaic (PV) as an electricity supplier and discusses the most important factors which affect the promotion and expansion of PV systems.` In between “af” and “fect”. ![Screenshot 2023-12-26 at 11.32.04 AM](https://us1.discourse-cdn.com/flex020/uploads/crossref/original/2X/d/d4b630cdd8ec5ecb20947ee6ec7512a50eaa218f.png) The solution is the same. You will need to resubmit the metadata using the Web Deposit Form, but ensure that the text is plain text, without formatting.
