Fixing justificiations?

[exachillus]

Hi

I converted a pdf to epub but when I looked at it on my ereader I see it like below

"
The creation of anagrams assumes an alphabet,
the symbols
which are to be permuted. In a perfect anagram, every
letter must be
used, with exactly the same number of occurrences as
in the anagrammed word
or phrase; any result that falls short is called a subliminal anagram[citation needed]. Diacritics
are usually disregarded (this is usually not relevant for English anagrams), and standard orthography is to be used.
"

That is just a sample text. How do I fix this issue in Calibre so that it loks right in my erader?
