DLSoft Application Note 03971

dLSoft Barcode fonts for Windows not 
showing space character

Problem
A text string displayed or printed using one 
of the dLSoft barcode fonts for Windows does not 
display the correct symbol for a space character.

Cause
Many programs under windows do not use the space 
character to display a space on screen (or printer) - 
in fact they work out the position of the display of 
the next character after the space and start again 
from there. So for example, the string AB CD will 
be displayed as AB and CD with a gap between them.

Resolution
Using a barcode font cannot overcome this problem 
directly if the space character is not actually 
being displayed. However, all dLSoft barcode 
fonts for Windows reproduce the space character 
(ASCII 32) at ASCII 159. So the user needs to 
translate all space characters into ASCII 159 
characters for them to correctly display as 
the barcode symbol.

Note that this same problem arises with non-break 
space characters (ASCII 160) in some software, 
such as Word for Windows. Again the solution is 
to translate the ASCII 160s into ASCII 159s.
