Your code has a some strange character instead of spaces. If you copy the code below they should be replaced with real spaces and the problem should be solved.

//Sample using LiquidCrystal library
#include "LiquidCrystal.h"
// select the pins used on the LCD panel
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
// define some values used by the panel and buttons
int lcd_key     = 0;
int adc_key_in  = 0;
#define btnRIGHT  0
#define btnUP     1
#define btnDOWN   2
#define btnLEFT   3
#define btnSELECT 4
#define btnNONE   5
// read the buttons
int read_LCD_buttons()
{
  adc_key_in = analogRead(0);           // read the value from thesensor 
  // my buttons when read are centered at these valies: 0, 144, 329, 504, 741
 // we add approx 50 to those values and check to see if we are close
 if (adc_key_in > 1000) return btnNONE; // We make this the 1st option for speed reasons since it will be the most likely result
 // For V1.1 us this threshold
 if (adc_key_in < 50)   return btnRIGHT;

Code needs to be developed with a real programmers' text editor, not some fancy WYSIWYG tool,
since the character coding must be based on ASCII (ASCII spaces, quotes, double quotes, etc, not
fancy variants).
