How work with text data files

I try migrate from Unity to UE4 and everyone knows that games are powered by data
In Unity in all text files (.txt .xml .json, .html etc) supported and seen as TextAsset objects, but in UE4 I found that the methods of work with text data files is limited by .csv- FDataTableRowBase or field records in the ini file using UPROPERTY(config). But the editor does not see plain text files.

Is there a universal way to work with text files in UE4 that does not depend on the path to the file (if the game is being developed for multiple platforms - for example in Unity there Resourses folder from which you can load the files on any platform) and why the editor can not accept text files as a single resource type text?
Sorry for bad english
