Interlude Unichat

Hello Folks,

I looked quite deep in this forum and all subject related to unichat forwarded me to Fyyre website. My problem is that the link for the C1-C6 unichat patch is dead and I can't find it somewher else (spent like hours on the web without finding something relevant).
 

Does anyone have this patch ? or another working solution to implement accents in the game ?
 

Thanks in advance for your advises.
