EU4DLL

中文说明

This dll makes it possible to display double-byte characters on Europa Universalis IV.

Features about this fork

• Auto UTF-8 conversion: Localization files in UTF-8 are automatically converted to the game's internal encoding at load time. No need for pre-processing tools — just drop UTF-8 .yml files in and they work alongside traditional pre-encoded files.
• Steam Rich Presence fix: CJK text in Steam Rich Presence (e.g. country name, ruler title shown on your Steam profile) is properly displayed instead of garbled symbols.
• Checksum override: Bypass the game's checksum validation so achievements can be earned even with mods enabled.
• Linux support: Works under Proton/Wine via version.dll override.

Notice

• This project is unofficial.
• Supports EU4 v1.37.x only.
• Windows and Linux (via Proton/Wine) are supported. Steam only.
• macOS is not supported.

How to use

Windows

1. Download the latest release zip and extract it.
2. Copy version.dll and the plugins/ folder into the EU4 game directory.
3. Subscribe to multibyte mods from Steam Workshop, or add mods to the Paradox user directory.
4. Enable mods in the game launcher.
5. Play.

Linux (Steam Play / Proton)

1. Follow the same steps as Windows to place the files.

2. In Steam, right-click EU4 > Properties > Launch Options, and add:

   WINEDLLOVERRIDES="version=n,b" %command%

   This tells Wine/Proton to load the native version.dll from the game directory instead of its builtin one.

3. Play.

Note: If you remove the mod DLLs later, the game will still launch normally — Wine falls back to its builtin version.dll.

Spec

plugins/plugin.ini

SEPARATE_CHARACTER_CODE_POINT

Change the character that connects the region name and the country name. See ISSUE-164.

REVERSING_WORDS_BATTLE_OF_AREA

Change the word ordering:

• Battle of / xxx -> xxx / Battle of
• Siege of / xxx -> xxx / Siege of
• Occupation of xxx -> xxx / Occupation of

AUTO_UTF8_CONVERSION

When set to yes (default), UTF-8 encoded .yml and .txt files from mods are automatically converted to the game's internal escape encoding at load time. Vanilla game files are not affected.

STEAM_RICH_PRESENCE

When set to yes (default), fixes garbled CJK text in Steam Rich Presence display (country name, ruler title, etc. shown on your Steam profile).

ACHIEVEMENT_UNLOCK

When set to yes, patches the game's checksum comparison to always report "match", so achievements and multiplayer work even with mods enabled. Default is no.

Name order

Attaching Inverted Question Mark (¿) to dynasty, the first name and last name are reversed.

1534.6.23 = {
  heir = {
    name = "Nobunaga"  # Nobunaga
    monarch_name = "Nobunaga"  # Nobunaga
    dynasty = "¿Oda"  # Oda
    birth_date = 1534.6.23
    death_date = 1582.6.21
    claim = 90
    adm = 5
    dip = 5
    mil = 6
  }
}
# Nobunaga Oda -> Oda Nobunaga

When you use this feature, please exclude Inverted Question Mark (¿) from all fonts.
