odd characters inserted at end of string during sql server update

I have this query, it was part of another ee question but I cannot find the id now.

the query is working but ive spotted some odd additions at the end of the string output which shouldnt be there

the query is below. ive highlighted the attachment to show whats added

ive attached an xml output, i suspect its that space at the end causing this, can i get rid of that during the update sql, if indeed thats what it is.

<TblWords ClientCodeWordPosition="07130219__5" StrFull="320 D GT LUXURY " StrShort="320 D GT LUXURY &amp;#x20;" />
<TblWords ClientCodeWordPosition="07130219_320_1" StrFull="320 D GT LUXURY " StrShort="320 D GT LUXURY &amp;#x20;" />
<TblWords ClientCodeWordPosition="07130219_D_2" StrFull="320 D GT LUXURY " StrShort="320 D GT LUXURY &amp;#x20;" />
<TblWords ClientCodeWordPosition="07130219_GT_3" StrFull="320 D GT LUXURY " StrShort="320 D GT LUXURY &amp;#x20;" />
<TblWords ClientCodeWordPosition="07130219_LUXURY_4" StrFull="320 D GT LUXURY " StrShort="320 D GT LUXURY &amp;#x20;" />

use Dictionary
go

WITH Filtered
AS ( SELECT W.Word, w.WordPosition, w.clientcode, w.ClientCodeWordPosition, w.StrShort
    FROM tblwords w
		LEFT JOIN tblwordtags wt ON W.clientcodeWordPosition = wt.clientcodeWordPosition
    WHERE wt.word IS NULL)

UPDATE tblwords
SET StrShort = RTRIM((SELECT I.Word + ' '
			FROM Filtered I
			WHERE I.clientcode = tblwords.clientcode
			ORDER BY i.WordPosition

			FOR XML PATH('')))
