I have a long book in rtf which I am concurrently reading on Kindle & editing via Word + calibre conversion to improve paragraph structure & spelling. I guess it was originally a PDF.

now, only after upgrading to 7.2.26 of calibre I'm seeing occasional word split strangeness i.e.

" a sentence which looks fine in word"

will , on conversion, become

" a sente

nce that does not look fine in mobi"

i.e. the calibre conversion infrequently split a word that is not split in the rtf, and will also add a blank line, as per the made up example above . I am at a loss to explain this. I see it both on Kindle & in calibre's own mobi reader, so it is not a kindle bug. it is infrequent, say one word per 1000 is affected, but it is still annoying. I have turned off optional all structure detection processing options for the conversion

I have also tried select all + copy to new blank doc + save again as .rtf in Word, in case mutilple edits were affecting the source file but that has not fixed anything. The text flows fine in word with no strange characters, and the words that are being split do not show up as issues in word spell / grammar check

If I go to the .rtf, /delete retype the broken word & reconvert, that fixes that word, but another random split will occur later on.

I've been working on & reading this for a couple of weeks now & only started seeing this issue yesterday.

any thought / clues on what to look for ?

did the latest release make any changes to how rtf to mobi works ?
