Erland,

I've submitted a workaround to this Feedback item. If you
concatenate the empty string '' to the CHAR value before
REPLACE is applied, the hidden conversion to VARCHAR
retains the trailing blanks.

declare @t char(6)
set @t = 'A'
select
replace(@t,space(1),'*'),
replace(@t+'',space(1),'*')
