I provide Arduino tutorials for my breakout boards we make. I have a tutorial for the HMC5883L. When the example is loaded in the Arduino IDE, by going to File > Example > HMC5883L > HMC5883L_Example the file loaded has an odd single quote character at the start of the sketch. This is not in the ino file in the library directory, but causes the application not to compile.
You can remove this character and it does not return, meaning you can compile the sketch. However to other users it appears that the sketch is broken :(
Please could someone help me resolve this? Here is a link to the library: http://c48753.r53.cf3.rackcdn.com/LoveElectronics_HMC5883L_ArduinoLibrary_V3.zip
Here is picture of the bug:
