Displaying '&' symbol in TraySetToolTip()

[anonymous]

Below code will only display "hi" when mouse is placed onto of the tray icon.

TraySetToolTip("hi&")

I've tried escaping the '&' symbol, which isn't necessary, but doesn't work. Is this a bug? At least I think it is.

This is not a bug. By default, Tooltip controls strip the ampersand character. You can either change the style of the tooltip to add the TTS_NOPREFIX style or you can triple the ampersand to get it to display.

TraySetToolTip("hi&&&")

The reason three ampersands are required is because it's double-escaping. The first escape is to prevent the ampersand from being stripped and the second escape shows a literal ampersand instead of underlining the next letter.
