Character Identifier is a Web Extension that adds a browser context menu item for selected text that provides more information (from the Unicode database) about the characters selected.

It was previously (in this same repository) a Firefox extension using the old XUL-based Firefox extensions API. As a Web extension, it works in both Firefox and Chrome, but crashes the entire browser reliably in Edge, perhaps due to Issue #10831621.

Build it by running make. The unpacked output will be in output/, and the packaged extension will be in char-identifier.zip.
