I can give you 2 scripts that do the same but the first dumps the data "as-is" (suggested) while the second one converts unicode to utf8:

Code:

set MEMORY_FILE binary "\xff\xfe"
get LBF_SIZE asize
for OFFSET = 0 < LBF_SIZE

    get DATASZ variable2
    math DATASZ * 2
    getdstring DATA DATASZ
    set DATA unicode DATA
    set NAME string DATA

    get DATASZ variable2
    math DATASZ * 2
    savepos OFFSET

    log NAME 0 0
    append
    log NAME 0 2 MEMORY_FILE
    math DATASZ - 2
    log NAME OFFSET DATASZ
    math DATASZ   2
    append

    math OFFSET   DATASZ
    goto OFFSET
next

Code:

get LBF_SIZE asize
for TMP_OFF = 0 < LBF_SIZE
    callfunction GET_DATA 1
    set NAME string DATA
    callfunction GET_DATA 1
    savepos TMP_OFF

    log MEMORY_FILE 0 0
    putct DATA string -1 MEMORY_FILE
    get SIZE asize MEMORY_FILE
    log NAME 0 SIZE MEMORY_FILE
next

startfunction GET_DATA
    get DATASZ variable2
    math DATASZ * 2
    getdstring DATA DATASZ
    set DATA unicode DATA
endfunction

Thank you for help. But somehow the scripts are not working.

On the internet I found unrollers for the first part, and the unpacked archive. There was one file. Now we need someone to help export and import text from a file. Text file attached.

Open it with a hex editor and add the bytes 0xff 0xfe at the beginning.
The first script I pasted does this operation automatically when extracting the files.
