Determine whether a MIME type is text data.


The istext function in Julia is used to determine whether a given MIME type represents text data. Here are some examples of how it can be used:

  1. Check if a MIME type is text:

    julia> istext("text/plain")

    This example checks if the MIME type "text/plain" represents text data.

  2. Handle different MIME types:

    julia> mime_type = "application/json"
    julia> istext(mime_type)

    It checks if the provided MIME type, in this case "application/json", represents text data.

  3. Check multiple MIME types at once:
    julia> mime_types = ["text/html", "application/pdf", "image/jpeg"]
    julia> is_text = [istext(mime_type) for mime_type in mime_types]

    It checks multiple MIME types at once and stores the boolean results in an array.

Common mistake example:

julia> istext("image/png")

In this example, the mistake is assuming that all image types are considered text. It's important to understand that istext specifically checks if a MIME type represents text data, and not all MIME types are text-based.
