I want to change this:
...
%%%23begin
aaaaaaa \
bbbbbbb \
ccccccc \
%%%23end
...
to this
...
%%%23begin
xxxxxxxx \
yyyyyyyy \
zzzzzzzzz \
tttttttt \
%%%23end
...
the number of lines might change after editing.
using this function :
function editEntry(){
local entryIndex="$1"
local pattern='^%%%'$entryIndex'begin'
d1=$(grep -n "$pattern" "$theBook" | cut -d: -f 1)
d1=$((d1+1))
local pattern='^%%%'$entryIndex'end'
d2=$(grep -n "$pattern" "$theBook" | cut -d: -f 1)
d2=$((d2-1))
local text1=$(sed -n "$d1,$d2"p "$theBook")
echo "$text1" >| "$tmpfile"
gedit "$tmpfile" && local text2=$(cat "$tmpfile" )
sed -i "s@$text1@$text2@" "$theBook"
}
apparently sed does not change entire paragraphs , it only operates on lines

What change do you want to make? It looks like you want to operate on the lines between23beginand23end, is that right? Please edit your question and show us your desired output so we can understand what you need.

Scripting text edits is what ed is for:
ed file <<'SCRIPT'
/%%%23begin/+1,/%%%23end/-1d
/%%%23begin/a
xxxxxxxx \
yyyyyyyy \
zzzzzzzzz \
tttttttt \
.
wq

First, delete the contents between (but not including) the markers, then append the desired text after the start marker. "Dot" ends input. Save and quit.

the function above is a part of a lager bash script that makes the file, and it contains arabic characters that's way I used gedit.

here is what I did based on your answer ` printf " /$pattern1/+1,/$pattern2/-1d n /$pattern1/a $text2 n . n wq n SCRIPT " | ed -s "$theBook" ` but it didn't work

If you want to use printf:printf '%sn' "/$pattern1/+1,/$pattern2/-1d" "/$pattern1/a" "$text2" . wq | ed -s "$theBook"-- the "SCRIPT" is the heredoc terminator, not an ed command.

What change do you want to make? It looks like you want to operate on the lines between
