Topic: character spacing ??

Hi,
Can someone tell me why the inter character spacing
for some characters is so far less than others in the
stream content ?

I am working on a program that replaces some text
string in [( )]TJ, and what I've found is that
if I simply replace the found pattern ignoring the
individual glyph value, if any, then for some
characters like B, E, F, G, W etc will all clump
together after the replacement!!
Is it a matter of setting correct glyph value for
these characters or do I need to adjust the Tm matrix
values ?

Can someone please point me to a good reference for
Tm matrix ? The description/explanation in PDF
Reference 1.3 isn't quite that clear to me.

THanks
