How to correct unicode errors after converting file format?

Question

To convert epub to mobi I utilized on online tool, but it seems to have resulted in odd unicode errors. Throughout the text there are 0092, 0093 and 0094 in place of punctuation.

Is this likely to to be a problem with the source material? Perhaps the author just used strange punctuation which results in hiccups and glitches during conversion? Or, is this more likely a problem with the online converter?

I'll probably have to convert manually with Calibre, which looks doable.

Might this be a problem with Amazon, or the Kindle e-ink reader itself?

There are some issues with sending azw or azw3 to Kindle cloud via e-mail.

Most online tools actually use Calibre as the conversion tool. I.e., you might as well use Calibre.

Throughout the text there are 0092, 0093 and 0094 in place of punctuation.

There's most likely a problem with the original epub file. You might want to check your epub with the IDPF validator before converting it with Calibre.

If the validator doesn't report any problems, open the file with Calibre Editor and search and replace all numerical codes with the equivalent punctuation characters.

When using Calibre to convert your epub files make sure to select AZW3 as the target format. For even better results install Kindle Previewer 3 and the KFX plugin and convert your epub files to KFX files.

Hopefully someone knows why this is happening and what I can do to fix it.

Thanks for the help!! reconvert with the checkbox in 'look & feel' that is labled 'transliterate unicode characters to ascii" checked.

The transliterate checkbox fixed my error, FWIW. The publisher is sterling, BTW, and, no I haven't, as of yet, checked that it's valid.

The Calibre note for that check box gives an example of going from Russian Cyrrilic to the English alphabet. Perhaps it's an internationalization problem.
