By relying on Unicode, Zotero can import, store, and cite items of any language.

Moreover, Zotero's user interface (menu items, tabs, etc.) also can be tailored to display in any language through the use of language localizations. Thanks to the tireless efforts of the BabelZilla community, we currently support the following languages in addition to US English:

• Arabic
• Bulgarian
• Catalan
• Chinese (simplified characters)
• Chinese (traditional characters)
• Czech
• Danish
• Dutch
• Finnish
• French
• Galician
• German
• German (Austrian)
• German (Swiss)
• Hebrew
• Hungarian
• Italian
• Japanese
• Korean
• Norwegian
• Polish
• Portuguese
• Portuguese (Brazilian)
• Romanian
• Russian
• Serbian
• Slovak
• Slovenian
• Spanish
• Swedish
• Thai
• Turkish
• Ukrainian
• Vietnamese

If you are running a localized version of Firefox, Zotero will automatically use that locale's interface if we support it. For example, if you download and install the French version of Firefox, your Zotero user interface elements will automatically display in French. If Zotero does not yet support the language used in your copy of Firefox, its user interface will default to English.
