Why does exit status 1 stray '\302' in program pop up around Serial.println ( "-> Second Service load");?
As Gerben notes, the stackoverflow question error: stray '\302' in program is about this issue.  Basically, your file contains one or more characters not valid in the current character set.  The character is either non-printing or a multi-byte unicode character.

How did the character get there? Some of the ways mentioned in the stackoverflow question are pressing ctrl-space or shift-space.

How to find the character and get rid of it?  You can look at output from hex-dumping the file, which will identify all characters definitively.  Or by trial and error you can delete and retype spaces in the region of the error.
