Copy from viewer to web form results in invisible characters being added

mfaine1 · 01-02-2024, 06:38 PM

I'm reading a book in Spanish and trying to copy the words I don't know into a web form and additional characters are being added, for example:

or*gu*llo*sos

When pasted into a search form at SpanishDict.com becomes:

or%C2%ADgu%C2%ADllo%C2%ADsos

Is this an option or something that I can turn off to prevent this?

Thanks
Mark

Those are non-breaking spaces. If they are present in the text they will be present when copied as well. The viewer has no way to know whether the non-breaking spaces are safe to replace with ordinary spaces or not.

I can't imagine a scenario in which copy and pasting non-breaking spaces as normal spaces would matter though I could be wrong. Still, would it be possible to replace invisible characters (such as this) with a regular space either globally or at the book level? It kind of breaks the copy/paste functionality otherwise. I think in 100% of the cases the user is not going to intend to copy non-breaking spaces to the clipboard.

I would definitely expect non-breaking spaces to be preserved when copying text. non-breaking spaces often have semantic meaning. And if you want to replace then use search and replace either via the edit book tool or by doing a conversion from whatever format the book is in to the same format.

Perhaps a minor nit but if I recall correctly, %C2%A0 would be a non-breaking space. %C2%AD would be a soft hyphen.

Ah in that case you can use the Polish books tool in calibre to remove them automatically.
