I ran into a rather odd glitch. One author that I do so work with changed the program they used to generate ePubs. One result is the misuse of <i> tags.
This is what I would expect to see:
Code:
<i>This is an italic sentence</i>.
This is what the misbegotten program generates:
Code:
<i>This</i><i> </i><i>is</i><i> </i><i>an</i><i> </i><i>italic</i><i> </i><i>sentence</i>.
And CustomCleanerPlus removes the <i> </i> strings so what pops out is:
Code:
<i>This</i><i>is</i><i>an</i><i>italic</i><i>sentence</i>.
Thisisanitalicsentence.
I worked around it by converting the <i> </i> to a simple space (ditto for the <b> </b> but they were a lot rarer before doing much else.
