    When including files from external sources, it is sometimes desirable to look at the content (at least the beginning of the file) in binary form.

    For example, transmitted CSV files occasionally cause surprising crashes because the header line does not seem to be evaluated as expected. This is because the file was saved as "UTM8 with BOM character" by the sender.

    A quick look with Notepad++ does not always help, because the visible result depends on the current "Encoding" setting.​

    If no hex editor is installed locally, the use of the fast "hexed.it" can help to evaluate the contents of a file: https://hexed.it/

    Erel provides a function for handling BOM here: https://www.b4x.com/android/forum/t...utf-8-file-that-might-have-bom.90943/#content

    Note that you can see it with Notepad++:

    Option 1: check the encoding:


    Option 2: View the content with hex mode:

    Is that a plugin? I don't have those icons on my Notepad++ toolbar.

    Yes. Open the Addonmanager, search for HEX, install the HEX-Editor

    Thanks. Unfortunately the plugin is not high dpi aware so the characters are HUUUUUGE on my Surface Studio so I'll have to stick with HxD for the rare occasion I need to get down and dirty!
