Hi Kadir,
I think "xa0" is code for a non-breaking space (an artefact left over from when the srt files were created maybe?). If you do a search and replace in Word (searching for ^s and replacing it with a regular space) that might fix it. I imagine "xe" and "xf" are codes for other special characters but, offhand, I’m not sure what those are. Better yet, I wonder if running your Word doc through AntFileConverter might get rid of those special characters and save you doing a manual search and replace.
Don't know if this helps or not.
Take care,
Dax
