I am working on my PhD thesis and have a huge file to compile. In the package file, I included the following package and commented chapter by chapter but still, I get this error. I'll appreciate if you can help me to solve this issue. I am compiling by pdflatex and using the BibTeX for the bibliography.
P.s. error is about this character (â) but I do not have this character in my file.
Package ucs Error: Unknown Unicode character 128 = U+0080, (ucs) possibly declared in uni-0.def. (ucs) Type H to see if it is available with options.
