Hi Fabrice,
first of all, thank you for your fantastic job, BaseX changed my life !
Wow, that sounds like an important event ;)
Do you plan to let users set a custom separator when importing in CSV mode ? (the comma, semicolon, or tab are too restrictive)
Which separators characters would you like to have added? The reason for having defined fixed characters is that they are easier to specify via commands, but we could e.g. additionally allow numbers as input, which would then be interpreted as Unicode codepoints (32: space, etc.).
