encoding.2da is used for language encoding UTF8 mappings. It is one of the few 2da files not included in the game files by default (leading to default engine behaviour).
This was added in the NWN:EE 1.87.8193.35 patch of the game.
A module can ship a custom encoding.2da file that just looks like:
2DA V2.0
Codepoint
0 0x0
1 0x1
2 0x2
3 0x3
4 0x4
5 0x5
6 0x6
... |
This specifies a mapping between UTF8 (Basic Multilingual Plane only, i.e. codepoints <=0xFFFF) and whatever internal game codepage is. The module would also need to ship an appropriate set of font files that contain the same symbols at values 0...255.
As an example, Turkish is not a supported language, and Turkish characters such as ğĞşŞ cannot be typed. However, the Turkish codepage (ISO 8859-9) is very similar to the English/western one (ISO 8859-1), except that it replaces Icelandic characters (ðÐþÞ) with Turkish ones.
For a module to support Turkish, they first modify the English font and make the ð glyph look like ğ. Then, in the encoding 2DA they change the line 240 from 0xF0 to 0x011F. Players then type the unicode symbol ğ into the chatbar, but it's remapped to ð instead; however, the font displays it as ğ, so the player is none the wiser. When it comes time to convert it to UTF8 the reverse mapping is done, so the UTF8 text remains the same.
Only drawback is if you dump the cp1252/ISO8859-1 text to a file somewhere and then open it with a different program, you'll get gibberish.
| Column Names | Example | Valid Values | Description and Notes |
|---|---|---|---|
| Codepoint | 0x1 | UTF8 codepage IDs | See usage above. |
This is the games original unchanged encoding.2da if it was included in the game files.
