Hi after reading your post it sounds like a Armory wallet. If you look at how to restore armory backups they are separated in 4 characters. Maybe you use question marks to divide the characters. I would try to restore your wallet with Armory and see if it works. You will need to probably try different settings. Go and read how restore let me know how it works.

 Hi, it sounds like encoding is not working. Try this and see what happens
Follow these steps open Notepad on your computer

1- Copy the original text

2- In Notepad, open new file change Encoding -> pick an encoding you think the original text follows. Try as well the encoding ANSI as sometimes Unicode files are read as ANSI by certain programs

3- Paste

4- Then to convert to Unicode by going again over the same menu: Encoding -> "Encode in UTF-8" (Not "Convert to UTF-8") and hopefully it will become readable

The above steps apply for most languages. You just need to guess the original encoding before pasting in notepad, then convert through the same menu to an alternate Unicode-based encoding to see if things become readable.

Most languages exist in 2 forms of encoding: 1- The old legacy ANSI (ASCII) form, only 8 bits, was used initially by most computers. 8 bits only allowed 256 possibilities, 128 of them where the regular latin and control characters, the final 128 bits were read differently depending on the PC language settings 2- The new Unicode standard (up to 32 bit) give a unique code for each character in all currently known languages and plenty more to come, if a file is unicode it should be understood on any PC with the language's font installed. Note that even UTF-8 goes up to 32 bit.

  Hi, maybe we can try this. Go in bitcoincore and use list descriptors true command. This will output the descriptor and master priv key. Then once you have that key, go download electrum wallet from www.electrum.org. Start create standard wallet, then next select use master key then type your key from bitcoin core. Your address should show in view tab im not sure if it support bip32 but well see. Maybe you can find your address you had the money in. If it doesnt work we can try something else. How much was the loss?
