There are currently many encoding options (see also: Input Tool Has Limited Varieties of Code Pages) that are available for use with Alteryx Designer (https://help.alteryx.com/2018.2/CodePages.htm), however only a certain number of them can be directly accessed from the interface. Providing the user an option to enable all possible encoding options (from User Settings) for the applicable tools could eliminate the need for building an analytic app just to pass the output encoding parameter to i.e. the Input/Output/Run Command tools.
One case this could be useful is when there are file/folder names with non-English characters and a Run Command tool is used to execute an operation regarding moving something from/to the folder, where the only option is to use an OEM encoding to be able to correctly pass the file/folder name information, otherwise the characters are not read correctly by CMD.
