Displaying superscripts or subscripts in a standard text file is not possible due to the limitations of ASCII, which does not support these formatting options. To achieve this effect, one must use HTML with super or sub tags, LaTeX with a renderer, or a word processor that allows for annotation of these elements. Markdown files can also be used, but they require rendering to visualize the superscripts and subscripts. The simplicity of text files, which contain only plain ASCII characters without hidden formatting, results in smaller file sizes compared to word processor documents that include additional invisible characters for formatting.
