Some characters misplaced when using gs to convert ps to pdf

[Pascal Chantriaux]

Hello,
I want to convert a rtf document into a pdf one.
I work with windows me and word. I print
my rtf document in a file through a postscript
printer driver and then I convert the ps file
produced with gnu-ghostscript 6.53.
With this process, some of  the ' caracters
(very frequent in french) are followed by a
misplaced blank space when using a truetype
font like arial or times (which is converted
into type1 one).
I tried many postscript drivers, others softwares
like openoffice and afpl-ghostscript 7.04 and
I had every times the problem.
Is it a known bug?
Thanks for a little help.
