I got below errors durning cmake build, when I look at the circular_q.h I don't see any special character in that. I got the source files stright from the git. Any guys have ideas about this problem?

Same problem answer: #2012 (comment)

Visual Studio determines the source code encoding from the OS language settings.
Visual Studio loads the source code as Code Page 950 (Chinese).

C:\dev\ros2_foxy\build\spdlog_vendor\spdlog-1.5.0-prefix\src\spdlog-1.5.0\include\spdlog/details/circular_q.h(1,1): warning C4819: The file contains a character that cannot be represented in the current code page (950). Save the file in Unicode format to prevent data loss

Set compiler option /source-charset:utf-8 (or /utf8) to change the character encoding of source files recognized by Visual Studio.
