What are the present codes for space and linefeed characters? How can I be sure of which code works with each device?


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. The following example code demonstrates this.
#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;
    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
