Charset or The Charset Project is a collection of mods by asie. The name and design of the mod is based on the idea of a "character set"; each module contains a small portion of functionality and they can be toggled individually.
The mod has been forked and maintained by Vazkii between versions 0.3.0-pre10 and 0.3.0-pre15, however it was picked up by asie again for version 0.3.1 and beyond.
The name of the mod is often pronounced by the mod author and others as /kɑɹ.sɛt/ (like car-set); the "h" is silent.
Each Charset module usually performs a specific function, such as adding a few blocks or items for a specific feature or a tweak. These modules can toggled in the modules.cfg configuration file. Each module has a category and then a name, in the format of <category>.<name>, such as misc.pocketcraft. Certain modules have more granular names, such as tweak.remove.recipeBookButton. Since Charset 0.4.2, each module also contains a "profile". Four profiles exist:
STABLE, designating a module ready for modpack usage,
TESTING, designating a module ready to be used in a world, but with a higher likelihood of breaking gameplay/balance changes,
EXPERIMENTAL, designating a module ready to be tested by players, but with a higher likelihood of instability and missing functionality,
INDEV, reserved for modules only available in a development environment.
