When compiling the examples in the openFramework, if you encounter the below errors:

• “IntelliSense: too many characters in character constant    …icons.h” or
• error C2001: newline in constant (see below Fig.1)

The most likely reason is that you are using a non-English Windows or in the regional setting (from control panel =>Regional language => Adminstrative => System locale), the non-unicode language is not English. Double click the above errors in the C2001 error shows the details, as shown in Fig.2
