TypeScript compiler error TS1127

Issue

TypeScript Version:

1.8.10

Hi.

I still have the error code TS1127 when I try to compile a file. I use the code from the quick tutorial.

Code :

 function greeter(person: string){
      return "Hello, " + person;
    }
    var user = [0, 1, 2];
    document.body.innerHTML = greeter(user);

Expected behavior:

_greeter.ts(7,26):_Supplied parameters do not match any signature of call target_

Actual behavior:

greeter.ts(1,1): error TS1127: Invalid character.
greeter.ts(1,2): error TS1127: Invalid character.
greeter.ts(1,3): error TS1127: Invalid character.
greeter.ts(1,4): error TS1127: Invalid character.

Solution

(1,1): error TS1127: Invalid character.

The file contains an invalid unicode character at position 1,1

QuickFix

Create a new file and make sure it just contains the right characters

Better fix

Use a hex editor to figure out what went south.
