boards.txt compile error when uploading

Property line '?' in file C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt is invalid

Error compiling for board Arduino/Genuino Uno.

I am not sure what this error means. There are no ? marks in the text file and I cannot tellwhat Property line the error is referring too because it does not give a line number. The last part of this list is what I added to the boards.txt file before my compile stopped working.
I am running Ardunion 1.6.12 on Windows 10. Intel i5
Here is my boards.txt file. I've tried clearing whitespace in Notepad++ but
I am not sure what is wrong with the file to give me this error. I had to attach a text file because of the word count...Here is the boards.txt file:

I believe this error is caused by boards.txt having the incorrect file encoding. Save it as UTF-8, restart the Arduino IDE and the problem should be solved.

Thanks in advance for any suggestions.

I suggest switching from 1.6.12 to 1.8.3 (or whatever is current. It is a good idea to delete or rename the Arduino15 directories before the install:
Arduino IDE 1.6.5r5 and previous: C:\Users(username)\AppData\Roaming\Arduino15
Arduino IDE 1.6.6 and later: C:\Users(username)\AppData\Local\Arduino15

I'm sorry that this is in spanish, but can anyone help me with this? I have no idea what this means and how to solve this.

Any help? It's really important.

There's something wrong with the file C:\Users\María\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.6.21\platform.txt. Did you edit that file?
