I'm using the classicthesis template with TeXShop version 3.52 (3.52) on OS X Yosemite 10.10.4 (14E46).

I've been using the command \textit for italics in my project successfully for more than a year, but have been recently getting a bizarre compiling error.

Please look at the console output as TeXShop console doesn't allow copying for failed compiles:

console output

Any ideas what might be causing this?

  • Not sure that the error actually is at that point. Could you try making a fully minimal example and post that do others can test it?

  • Just in case: Did you check TeXshop saves your files in UTF8 encoding, not in applemac?

  • Open the log-file called classicThesis.log and copy the relevant part to the questionn as an edit.

The string \textit{test} consists of ASCII characters, which are not touched by package inputenc. The string only happens to appear on the line of the error. The problematic character is elsewhere on the line.

Often this error is caused by an unbreakable space character U+00A0. Delete the rest of the line or rewrite the whole line and try again.

Also a hex viewer can be used to analyze the characters on the line.
