arduino uno - GSM SIM900A

hello there. So I've been trying to send messages from my GSM to some phone number and I have found a code that is not working properly, I have connected Arduino RX - Gsm TX , Arduino TX - Gsm RX , and Arduino GND - GSM GND.
the code wil be linked, and this is waht the Arduino software tells me after running the code:

exit status 1
stray '\240' in program

what does that mean?

thanks for the help

this is waht the Arduino software tells me after running the code:

The Arduino software is the IDE. It does NOT "run the code".

The compiler is trying to compile the code, and is telling you that there is some character, somewhere in the file, that it does not recognize.

Check particularly for odd looking single quotes. A pair of printer single quotes will curve towards each other. A pair of programmer single quotes will not.
