Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com - MPGuino custom characters? Some optimisation suggestions

Hey,
has anybody made custom characters which are more descriptive than "LK" example?
I somewhere saw pictures, where somebody had made custom characters for example "L/100km" - it was made with 2 chars - first char was showing "L\n/1" and second "km\n00" - "\n" means newline - so imagine it as
"L/ km"
" 100"
Would be nice to know how to make them or link where I can get info.

One good hack/optimisation for code also:
I put clear screen commands before every screen change - now that half second when it shows screen name, it is only name - second line is clear. Now you can delete all trailing spaces in screen names and other strings. As a result you should save some bytes (did not count but it was less than before and screen names are clear to read)

inside setup()

Code:

  

  LCD::LcdCommandWrite(B00000001);  // clear display, set cursor position to zero         

  LCD::LcdCommandWrite(B10000);  // set dram to zero



  //LCD::gotoXY(0,0); //no need for it, clear display already made gotoxy(0,0)

  //LCD::print(getStr(PSTR("OpenGauge       ")));

  LCD::print(getStr(PSTR("OpenGauge")));  



  //LCD::gotoXY(0,1);      

  //LCD::print(getStr(PSTR("  MPGuino  v0.75"))); 

  LCD::gotoXY(2,1);      

  LCD::print(getStr(PSTR("MPGuino  v0.75")));

inside loop()

Code:

   //LCD::gotoXY(0,0); //no need for it, clear display sets it gotoxy(0,0)

   //is any of three buttons is pressed, clear display

   if( !(buttonState&lbuttonBit)  || !(buttonState&mbuttonBit) || !(buttonState&rbuttonBit) ){

      LCD::LcdCommandWrite(B00000001);  // clear display, set cursor position to zero

   }



   //see if any buttons were pressed, display a brief message if so      

   if(!(buttonState&lbuttonBit) && !(buttonState&rbuttonBit)){

      LCD::print(getStr(PSTR("Setup"))); //remove trailing spaces "Setup " -> "Setup"

      initGuino();

   }

   //....code continues
