[NTG-context] XML, multiple spaces encoded as %20 get merged into one space

6 Sep 2023

      Hi,

I have the example below that uses the three images in the attachment.
For some reason multiple spaces encoded as %20 get merged into a single %20.

The first image (<test  two20spaces.pdf>) does not get included even though the name is correct.
The second image (<test one space.pdf>) gets included. Filename is correct.
The third image (<test not two space.pdf>) gets included even though the actual file name does not contain two spaces (but @xlink:href does).

Any ideas what is going on here?

Then, in the case of the link, the two %20 end up as a single %20.

Best,
Denis
