<para>After installing the Bijoy fonts and keyboard, one may be tempted to use them for purposes other than creating PDFs. But a little common sense and
|
||||
farsightedness will reveal that the use of a nonstandard font and keyboard like
|
||||
Bijoy is destined to create the same kind of chaos regarding Bangla in the Open
|
||||
Source environment as is now prevailing in the proprietary world. PDF is a
|
||||
different story though as they are font independent(if created properly) and
|
||||
has no chance of getting into this kind of chaos. Now what if one needs to
|
||||
create a Bangla text file? Easy - use Unicode. Recent developments has made it
|
||||
possible to write Unicode based Bangla in GTK+ 2.0 (or higher) based softwares.
|
||||
And the same thing is on the offing for QT (which is the backbone of KDE).
|
||||
Even PDFs can be created from Unicode encoded Bangla text files. This has been
|
||||
described in a later <xref linkend="unicode"/>. So instead of relying on
|
||||
nonstandard softwares like Bijoy, try to use Unicode based Bangla wherever
|
||||
possible. </para>
