Custom linker won't compile

I'm trying to reserve space in RAM for emulated eeprom. I can read and write fine, however when I try to modify the linker it won't compile.

The added user section

/* Specify the memory areas */
MEMORY
{
 FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 96K
 USER_DATA (rwx) : ORIGIN = ORIGIN(FLASH) + LENGTH(FLASH)‬‬, LENGTH = 32K
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 8K
 MEMORY_B1 (rx) : ORIGIN = 0x60000000, LENGTH = 0K
}

Howerver when trying to compile it says «invalid character» at the line of the new section in the linker script:

You have unicode characters in your script which should be strictly ASCII.

Delete the line it's complaining about and retype it on the keyboard. Don't copy/paste.

It did the trick, I used a different editor as well.
