Passages with spaces joined by periods rather than split into separate words

[gordonbisnor]

We have noticed an issue where in somes cases pieces of our text are joined by periods into one massive word, rather than split by spaces into individual array members, eg:

[1027,54,538,27,38,"Churches.set.up.Christian.schools.in.the.early.1800s..Some.Indigenous.peoples.were."]

Not sure if you have any idea what might cause this – if it’s an issue in our PDFs or something that pdf2json is getting wrong for some reason?
