How do I insert special characters in WolframScript using an international keyboard?
When trying to input special keys such as {,[,] and } in WolframScript using an international keyboard, WolframScript may not be able to produce the characters with the default launching option.
To resolve the issue, start WolframScript in raw mode:
wolframscript -rawterm
When in raw mode, the kernel accumulates all bytes it receives from the keyboard directly in the input buffer for further parsing and interpretation.
This raw mode disables some default keyboard shortcuts such as Ctrl+A, Ctrl+D, Ctrl+E, Ctrl+G, Ctrl+K and Ctrl+Z for editing the input, but it enables the {,[,] and } keys.
