Here I used awk to replace everything except "#" on your "§" line with spaces. This is used as a template to insert the required comments:
Code:
awk -v D=2019_08_25 -v V=34-1-9 -v M=9-7-3 '
function com(str) {
   print substr($0, 0, pos - 1) str substr($0, pos + length(str))
}
/§/ {
   pos=index($0, "§")
   gsub(/[^# \t]/, " ")
   com("§" D "§")
   com("")
   com("¨version:" V "¨")
   com("")
   com("ɸmodif_version:" M "ɸ")
   skip=1
}
/ɸ/ && skip==1 { skip = 2 ; next }
skip == 1 {next }
1' "$SOME_FILE"

This helps the formatting to match:
Code:
#!/bin/bash
