I am really missing the point or you guys are.:)
I find the location of a string with offset
I take that location and decrement it by 1
I use ASCII to tell me what that character is
I concatenate ASCII's results before the string which was initially
found
Offset says it cannot find that string.
Is it possible that ASCII is just returning the low byte of a non
printable multibyte character but offset is expecting all the bytes
of the non printable character?
I wrote a handler
tell application "Safari"
set myText to the text of document 1
set myOffset to offset of " Departing " in myText
end tell
tell application "TextEdit"
set tt to ""
set lowerLimit to myOffset - 10
set upperLimit to myOffset + 10
repeat with i from lowerLimit to upperLimit
set tt to tt & i & " " & (text i of myText) & (ASCII number
(text i of myText)) & "\n" as text
end repeat
set ttt to text lowerLimit thru upperLimit of myText
set the text of document 1 to tt & "\n\n\n" & ttt
end tell
with the following text

1962 n110
1963 g103

Departing
After the three returns (1950-1952) there is a non-printable
character at 1953. ASCCII is returning only 'part' of it. That part
isn't sufficient for offset to match it.
The character whose ASCII is 63 isn't a non printable exotic
character, it's the letter "c"
The character whose ASCII code is 32 is the space.
Why are you using ASCII which is fooled by Unicode characters ?
Apple carefully delivered it's successor s:
ASCII character --> character ID
ASCII number --> ID
