UIDs of odd length.

[Brian O'Brien]

Has anyone noticed if UIDs of odd length are terminated in 0x00 or 0x20 when written to Part10?

[Darcy Mason]

According to the standard, they should be null-terminated: https://dicom.nema.org/medical/dicom/current/output/chtml/part05/chapter_9.html#sect_9.1

If I'm not mistaken they are currently padded with spaces instead of nul

[Darcy Mason]

Shouldn't be - checking the code, `write_UI` passes a `\0` to `write_string`, which does seem to use the passed value for padding.

However, if the original read from a file came padded with a space character, pydicom might write that back unchanged if the value had never been accessed (and therefore decoded, forcing pydicom to encode it when writing back).
