On S60 2nd Edition, Feature Pack 1 and earlier, the following codes (hex values) are used for linefeed and space symbols:

Linefeed:  0xe125
Space:     0xe118

Starting from S60 2nd Edition, FP2 and the Nokia 6630, these character codes have been changed to be the following:

Linefeed:  0xf200
Space:     0xf201

It is possible to dynamically check what codes to use by checking if the current font includes these characters.

#include <fbs.h>
 
#include <openfont.h>
 
TUid fontUid = CEikonEnv::Static()->NormalFont()->TypeUid();
 
if(fontUid == KCFbsFontUid)
 
    {
 
    const CFbsFont* font = 
 
      static_cast<const CFbsFont*>(CEikonEnv::Static()->NormalFont());
 
    TOpenFontCharMetrics metrics;
 
    const TUint8 *bitmap1, *bitmap2;
 
    TSize size;
 
    font->GetCharacterData(0xe118,metrics,bitmap1,size);
 
    font->GetCharacterData(0xe125,metrics,bitmap2,size);
 
    if(bitmap1 == bitmap2)
 
        {
 
        // glyph bitmap pointers for space + lf have 
 
        // the same value, pointing to the same 'undefined'
 
        // bitmap -> Font does not have these chars
 
        // Switch to using 0xF200 and 0xF201 as lf/space codes
 
        }        
 
    }
