Please support Korean fonts

[magicianaos]

DF is a very popular game in Korea right now.
The recently released Steam version of DF's Korean translation participation rate is very good.

However, the DF font in the Steam version does not support Korean.
Can you support the tool that applies to the steam version DF and the Korean language to be output?

Hi
Technically this is possible, but this needs at least bringing back of rendering text using TTF fonts, and this is very tricky task.
Probably I'll try to do this, but not in the nearest future.

[magicianaos]

Thanks for your answer :)
We can support you.
Please tell me if you need anything.

Tarn is trying on SDL TrueType font rendering on steam edition.

[trotsky1997]

From where do you know it?

Sorry,I misunderstanded the update log, there was no sdl_ttf.dll now for steam edition

[trotsky1997]

This is just an outdated information. There is no more SDL_ttf.dll, no ttf font, no true-type font options (TrueType Font = TTF). Probably at some point of development of the steam version is was supported, but not anymore.

As for graphic font, anyone can edit the second half of the font (starting from the "funny" C letter, down below from it and to the right) to add their regional symbols, or an entire alphabet (if it is compact). The second half can contain 128 symbols, and in a text these symbols will be shown from left to right, so no compound symbols. So I presume you cannot use such font for Korean.

By the way, can you grant me a coordinator permission on the transifex platform? I'm working on chinese translation with friends and we may need a coordinator for the management of chinese localizations. thanks

As for the compound symbols, there were some potential similar solutions for English software with only single-byte support like Crusader kings, EU4, older GTA series.
The main difficulty of rendering double-byte compound symbols like CJK fonts and arabics is the rendering function of program only support the addressing of the single-byte symbols. What we need to do is hacking the addressing process and rendering function to add double-byte support.
This may lead to a violation of software's liscense policy. We can have a further talk if you have interest on.

我不知道如何制作如下图所示的字体来添加另一种语言。 我需要帮助。

Sorry my Asian fellow, DF only support single-byte font's rendering besides CJKs. We may need some hack to add double-byte support.

I rarely make anyone a coordinator. I do it only when I trust that person.

I can give you reviewer's permissions, but you need to tell me in translation to which language (or languages) you are intrested and your profile name on transifex.

ooo，i have analysed the coding page of DF steam edition, its encoding type was UTF-8,and in fact, the bitmap graphic image is enough to store the Chinese chracters in 8x12px!
I have been wrong in above comment for that the font rendering function of DF steam edition already support addressing of double-byte chracter. And what we need to do is add new chracter to the the bitmap graphic font image!
binggo! I'm trying.

[trotsky1997]

That was a demo for Chinese character's rendering with 8x12px,it would be better in higher pixel

[Juijote]

You can find some free pixel fonts here, I tested a couple of them, and they were pretty good .

[bitwalker37]

The display effect is quite satisfactory.

[trotsky1997]

[raydan]

由於只有 8x12px, 用圖片是沒有辦法顯示一個清晰的中文字

以下是個人測試後的結果
把 SDL ttf 用在 steam 上是可以顯示中文字

[raydan]

i use df-translate-hook for reference
load SDL ttf & replace the texrure

[trotsky1997]

i use df-translate-hook for reference load SDL ttf & replace the texrure

期待进展

[raydan]

now i can use the transifex po file to translate & display replaced word in game

"Set tree chopping orders."
the problem is the above string cut to two string "Set tree chopping " & "orders." pass to "addst"
which it unable to replace now, can not find any way to do that

i think it hard to display a clear chinese text right now even using SDL TTF.

korean text

@raydan can you share your code somewhere, please?

[trotsky1997]

It's perfect now. maybe you can share your code on github

[raydan]

ONLY FOR TESTING & POC, THERE ARE MEMORY LEAK

compile, rename dll to "df-steam-translate-hook.dll" and place to Dwarf Fortress.exe folder
copy "file" folder content to Dwarf Fortress.exe folder
rename "df_chs.csv" to "df_lang.csv"
rename "font_chs.ttf" to "font.ttf"

And i used df libgraphics for code reference
source code tested in v50.04

df_dll_test.zip

you may need to hook on textures::delete_texture to delete your cached texture
and hook graphicst::addcoloredst to make it like "addst" string replace, but i never found that address

I made texture swapping only in addchar, and in other hooks (like addst) just switch flag to swap.
And since i caching texture_id from add_texture, i obsreving no leaks in this moment... maybe there are some undeleted textures, but not so many, cause it not so many chars is use - it's not critical at all..
Now I faced with problem, where i have to find address for hook to very begin of loading save/new game. When we go from main menu (chose save for load or create new world) to this loading screen, its seems like game perform global mem clearing. And then my cache contains references to unexisting objects. So I need to reset cache exactly in this moment as well as game mem clear.

UPD: so, i hooked into loops of interface rendering (main menu and all kinds of loading/creating game) for game state tracking... reseting my cache whenever state changed to "game" from "menu"...

[shevernitskiy]

@raydan I found addcoloredst - 0x784890...
Now I working on strange issue. There are screen and screen_top (for dialog windows). Also there are addst_top, addchar_top and screen_to_texid_top - whole pack for different tile matrix. I successfuly hooked in the "top" pack. But when I trying to open ingame statistics table (Nobles and administrator for example) and popup tutorial windows appears in same time, text of main screen level become black. Don't now why, maybe i erased color or tex?

UDP: we need to use separate screen matrix for top layer, it solves an issue (or maybe we should find proper offset in main matrix for start point top layer)... but if we use just one screen matrix, layers may interfere - that corrupts data...

[mocksonline]

in 50.05 it doesnt work

[shevernitskiy]

in 50.05 it doesnt work

offsets slighly different in 50.05

As of 2025: due to the technical complexity of the task, we are not going to add support for Chinese/Japanese/Korean. We are going to focus only on languages with compact alphabets with left-to-right writing direction, with not too complex letters.
You can try to use dfint-rust-cjk, but it is a separate project, and we cannot guarantee anything.
Upd: for Korean try to use https://github.com/refracta/dfint-rust-cjk-ko
