I do this test with SQL Query Analizer 

create table #tmp1
(
        s varchar(7)
)
insert into #tmp1(s) values(convert(varchar,0x41414141))
insert into #tmp1(s) values(convert(varchar,0x41004141))
select len(s) as length,s,substring(s,3,2),convert(varbinary,s) from #tmp1

It produce this result

length      s              
----------- ------- ---- ----------
4           AAAA    AA   0x41414141
4           A AA    AA   0x41004141

So mssql can store null characters in string. 
Doing strlen to compute len of buffer just trim the string.
