To answer the last question, I'm in the Netherlands. However, I do not own the hardware I was reporting this bug on, and I can not test the different settings anymore.
Therefore I'm closing this bug report. I think that it should be possible to set an APN with a space (as other platforms like Android and Windows allow it) but as I have no way of adding information, I'm marking this as an opinion.
