I have been making icons for filetypes and has been successful except for the case of *.txt files. It gives me a File Sourcing Error saying Invalid filetype: ::*.txt and Invalid argument for :set command.
All the other icons work, but instead of having just one icon for all 'reg' (i guess it means registry) files, I would like the *.txt files to have a different icon so that I can quickly differentiate between config files and readme files (usually readme files are in .txt format while config files are not). I have made other custom icons (for `.iso` files, for example) and none of them gave me any issues about syntax.
Thanks for a great project, btw :)
