I have a similar question to this, I need subscript capital letters in an Excel chart, generated by a python script with xlsxwriter.
jmcnamara suggested to use UTF-8 Unicode. I need the letters 'IT' as subscript, as far as I now Unicode doesn't support those letters.
Any other ideas?
Apart from the Unicode workaround in the other post there isn't any way to do this in XlsxWriter. It is also unlikely to be supported in the future due to the API and internal complexity.
When answering the other question I thought that it might be possible to format the string in a cell and then link to it for the title. Unfortunately this doesn't seem to work in Excel and instead it shows the unformatted string.
So I don't know any other option unless openpyxl supports it, or xlwings.
