   None of Chris’s message is quoted in David’s message, so I don’t see how   
   that can be relevant.   
      
   I don’t see the C3... sequence you mention in 56g’s message:   
      
   # grep From: 34062   
   From: "56g.1183" <56g.1183@ztq4.net>   
   # hd 34062|grep c3   
   #   
      
   However David’s message does use U+00A0 (i.e. NO-BREAK SPACE, C2 A0 in   
   UTF-8), as part of the quoting of 56g’s message:   
      
   # tail +27 34073|base64 -id|hd|head   
   00000000  4f 6e 20 30 33 2f 30 31  2f 32 30 32 34 20 30 35  |On 03/01/2024 05|

   I think that’s a quoting decision made by Thunderbird, perhaps triggered   
   by an internal trip through an HTML representation where the redundant   
   multiple spaces at the start of 56g’s lines need to be converted to   
   something else to avoid whitespace collapsing.   
      
   Thunderbird’s decision to use base64 is certainly not what I’d do (NNTP   
   is 8-bit clean so Content-Transfer-Encoding: 8bit would be perfectly   
   adequate) but it is in-spec and has been for many years.
