Really 5 bytes, 'cuz you need a leading space (and a following space
if more text follows on the line) for proper decoding.  If the
"T123" is run right up against the end of the preceding text to save
some bytes, some software will likely pass it over.

On both of the web pages you show a leading space.  Let's hope
people don't forget to use it.
