Glypher

Insert any Unicode character into the focused application with a single button press.

Glypher runs on macOS and Windows and supports up to three independent characters per button via tap, double-tap, and long-press gestures.

Special Features:

Visual representation on the Stream Deck and selection in the Property Inspector

Unicode Line-Sep - a "return" that survives in a Slack message. (Slack removes extra lines that it recognizes.)

Business characters aren't on keyboards. µ, €, £, →, em-dashes, and similar symbols which otherwise require memorising obscure key combinations or using a character picker.

Zero-Width Space (ZWSP) — U+200B - an invisible character hinting that wrapping (breaking) at this point is allowed. i.e. best place in a very long string to break

Non-Breaking Space (NBSP) — U+00A0 - a visible space that prevents wrapping (breaking) at this point. e.g. between the title and name (Mr. Smith)

Addressed Icon background and Glyph placement concerns.
