Lisu is a Unicode block containing characters of the Fraser alphabet, which is used to write the Lisu language. This alphabet (and by extension the block) consists of glyphs resembling capital letters in the basic Latin alphabet either in their standard form or turned upside down. (The addition of the block was subject to significant debate as to whether an entire block was necessary for the alphabet or if the turned letters not already in Unicode could instead be added under the Latin script section. Ultimately, the former approach was taken, and the Lisu letters are thus semantically different from their Latin counterparts.)

This block is supported by a few fonts including Noto Sans Lisu, Lisu Unicode, DejaVu Sans, Horta, Montagel, Quivira, Segoe UI (since Windows 8).
