What version of Code::Blocks are you using? Are you using official RC2-installer final, are you using April 1st installer-RC2 Unicode, or are you using a nightly build ontop of either installer? Specify please!

That is because you have chinese characters (hanzis) on line 91 and 108. I don't know if GCC supports source files encoded in unicode (and if it supports, what type of encodings it supports), but certainly your actual configuration doesn't.

You can solve it in multiple ways, these are one of them:
1) Investigate if GCC supports unicode for source files, and if so, what encoding.
2) Use another compiler. For example, MSVC latest versions support UTF-8 and UTF-16 source files.
3) Don't use any unicode chars (use only ASCII chars) in your source files, and write all texts in plain english.
This is the most common way, and you will not loose unicode at all, because you can later translate the english texts to any language at runtime, using gettext catalogs. For creating the catalogs, here is a good GUI: http://www.poedit.org
