using the fact that part of the localization is not encrypted, I compare some lines. took as a basis the Spanish localization, here are a couple of lines from it:

Armadura temeria
Botas temerias

the English version of these lines are encrypted and look like this (hex):

0DEF D7DE 09BD B27A CFF5 13EB 95D6 99AD CE5B 9EB7 D76F 1FDF 9BBE AD7D
0DEF D7DE 09BD B27A CFF5 13EB 95D6 99AD CE5B 9DB7 CA6F 1DDF 80BE AC7D

I assumed that in the translation it should look like "Temerian armor" and "Temerian boots". hex view of UTF-16LE:

0DEF D7DE 09BD B27A CFF5 13EB 95D6 99AD  CE5B  9EB7 D76F 1FDF 9BBE AD7D
5400 6500 6D00 6500 7200 6900 6100 6E00  2000  6100 7200 6D00 6F00 7200
T    e    m    e    r    i    a    n     " "   a    r    m    o    r

0DEF D7DE 09BD B27A CFF5 13EB 95D6 99AD  CE5B  9DB7 CA6F 1DDF 80BE AC7D
5400 6500 6D00 6500 7200 6900 6100 6E00  2000  6200 6F00 6F00 7400 7300
T    e    m    e    r    i    a    n     " "   b    o    o    t    s

is clearly not a direct replacement character by (xor) or (shift), as the same characters in one string are represented by different codes. have any ideas?

It looks like a XOR with a long sequence of bytes but I don't know if it's a fixed "key" or is continuously generated byte-per-byte (like increment key + byte ^ key).

I waiting open tool editor tool and replace tool, for this files... Because this game have very hard language and We need it translate for game...

I absolutely agree with the SLaYeR983. And I want to translate this game...

Just for curiosity, can you upload the english and spanish w3string?

of course.

Is there any improvement?

so, decoding strings were similar as in the Witcher 2.

string_key = magic >> 8 & 0xffff
for (i = 0; i < strings_count; i += 2) {
    char_key = ((string_len + 1) * string_key) & 0xffff
    string_buffer[i+0] ^= ((char_key >> 0) & 0xff)
    string_buffer[i+1] ^= ((char_key >> 8) & 0xff)
    string_key = ((string_key << 1 ) | (string_key >> 15)) && 0xffff
}

Lua implementation is here. test output:

sorted.
done!

I do not know what to do with the second data block. also I do not know how to get linking between "item_category_light_armor_description" and "0x00109390" :(

ready strings from english part of dlc1:

0x001083ef ## Saddlebags allow you to carry more weight.
0x001083f6 ## A horse equipped with blinders won't panic as easily.
0x001083f7 ## A horse equipped with a saddle won't tire as easily.
0x00109390 ## Light gear. Increases Armor and Stamina regeneration.
0x00109991 ## Temerian Armor
0x00109992 ## Temerian Boots
0x00109993 ## Temerian Gauntlets
0x00109994 ## Temerian Trousers
0x00109996 ## Temerian Horse Blinders
0x00109997 ## Temerian Saddle
0x0010999f ## Temerian Saddlebags

Wow, you are awesome!
you can give directly tools? Unp/Repack?

This is good news...But, How to use this tool. This format foreign to me. preferably .exe format, as unpack.exe

There is a Gibbed red tool, for witcher 2. I guess, it will be help to you.

The Witcher 2 Gibbed Red Tool

Is there any news? Translate projects still wait, because of .w3strings file system...

Sarcenzzz on Nexus mod just released a tool to export and import w3strings file: http://www.nexusmods.com/witcher3/mods/676/?

Check it out.
