I have updated my plugin "Plugin for tidying ePub files" at
https://www.mobileread.com/forums/sho...d.php?t=264378 to enable a list of commonly misspelt words and their corrections in a separate file to be processed. The plugin uses the convention suggested by KevinH. Currently this plugin will change words that have been misspelt automatically, but not words where a context check is needed.
@theducks: DiapDealer has developed a plugin that will turn straight quotes to curly quotes at

While I appreciate that there is little point in using a plugin solely for correcting words when Sigil has a built in function for executing a group of saved searches, my plugin can do more than this. For example, it can process chapter headings, making them uppercase, mixed case etc and strip out unwanted tags at the same time, allowing the user to apply different options to different ePubs. It also has a "bolt-in" image resizer to change the siae of an image if it is too small for the cover page.
