It's odd that searching for "section" finds U+2E39 (Top Half Section Sign) but not U+00A7 (Section Sign).

The directions for input on on each operating system are all the same, use an app? On Windows there's a key sequence based on the codepoint integer. It should tell you exactly what to type. The Linux one is especially odd "Use the Character Map app or a Compose key sequence, then paste into your app" because if there's a compose key sequence you don't need to paste it.
