Remember, in the "standard typography" version "." and "I" are
unrelated. The glottal/pause is inherent in initial vowels and
words following "la"; the full stop is just the sentence-ending
blort.
No, it isn't; the "." is there *because of the "i". They are,
conceptually, directly attached to each other, so they should be
visually attached too. If there was no "i", there would be no ".".
Lojban does not require a full stop (if that's linguistically
different than a pause, which it seems to be?) anywhere, including
at the end of sentences.
