I know many questions already relate to this problem in LaTeX. However, I'm using LyX classicthesis and included the character ≥ by Insert > special character > symbol, and got this error Unicode char \u8:≥ not set up for use with LaTeX when trying to load the pdf. Since I just use the symbol provided by LyX and did not copy past it from different text, it should work? How does this error emerges and how can I solve it? If I just remove the symbol everything is fine, so it has to do with the symbol and not with some invisible space etc. I checked the classicthesis-config.tex, and there everything is fine:


Although when I want to load this tex file in TeXworks, I also got an error:


I also checked in LyX in Document > Settings > language, and it is put on utf8. Can somebody help me? Thank you!

    Not every unicode symbol is set up by default. If you want to use your symbol you must add a declaration, e.g. with newunicodechar. – Ulrike Fischer Apr 13 '17 at 19:52
  • I can solve it by inserting tex code $\ge$ but then the symbol is much larger than my other text, and also larger than the regular > sign. Can this be modified? – LHey Apr 14 '17 at 7:31
  • @LHey In Language settings, try using Unicode utf8x (extended) encoding (in all your child documents). This will make LyX call \usepackage[utf8x]{inputenc}. – PhilipPirrip Apr 14 '17 at 12:06
