Are there any specific features or plugins that PHP editors should have to support foreign language scripts effectively?

PHP editors should have features or plugins that support Unicode encoding and character sets to effectively handle foreign language scripts. This includes features like syntax highlighting for different languages, support for multibyte character encoding, and the ability to switch between different language settings easily.
