* Unicode support
* WSL/Cygwin/MSYS2 [support](https://github.com/ncruces/zenity/wiki/Zenity-for-WSL,-Cygwin,-MSYS2)
* on macOS:
* only dependency is `osascript` (with [JXA](https://developer.apple.com/library/archive/releasenotes/InterapplicationCommunication/RN-JavaScriptForAutomation/Articles/Introduction.html))\
JavaScript is easier to template (with `html/template`)
* only dependency is `osascript`
(with [JXA](https://developer.apple.com/library/archive/releasenotes/InterapplicationCommunication/RN-JavaScriptForAutomation/Articles/Introduction.html);
`html/template` makes JavaScript easy to template)
* on other Unixes:
* wraps either one of `qarma`, `zenity`, `matedialog`,\
in that order of preference
