Calibre has problems with three dots in image filenames

Ugh, apparently Calibre has problems with three dots in image filenames if I enable --smarten-punctuation option. Maybe I should report it to them when I stop being lazy.

Maybe replace the three dots (which are supposed to indicate an elipsis) with something else. Not sure what would be best. Some options are:

• underscore(s)
• hyphen(s)
• maybe '-xxx-'

Underscrores, single hyphen or -xx- will do. (there might be some issue with multiple hyphens, so it's best avoid that)

The --smarten-punctuation option in Calibre ebook converter converts plain quotes, dashes and ellipsis to their typographically correct equivalents.

Apparently, it doesn't skip all tags, so three dots ... becomes ellipsis glyph u2026. Actual images aren't renamed, so it can't find the referenced file.

I ran ebook-convert (Calibre ebook converter CLI) a few times and here is the console output: http://pastebin.com/9qPeRdsP

In the first run, --smarten-punctuation was on. It couldn't find the images. In the output, images got replaced with big blue question marks: https://i.imgur.com/UeB5ffb.png . Well, it's weird that it could find the cover image just fine.

In the second run, without --smarten-punctuation, it had no problem. The output is normal: https://i.imgur.com/XYqscv9.png

In the third and fourth runs, I edited the epub file in Sigil, and renamed images: three dots into two dots, a single dot, one/two hyphens, underscore, -xxx-, single quotes, etc. --smarten-punctuation was on, but it had no problem.

It seems that it only has problems with three dots. Underscores would be the safest, I guess.

That's a really detailed analysis.
Sounds like it is a bug in Calibre. As you say, it's renaming the tags.

I note this in the Calibre output, looks like I have more work to do.

The cover image has an id != "cover". Renaming to work around bug in Nook Color

Hrm thanks @dreamer2908 @toshiya44 for this detailed bug report. I agree with the -xxx- replacement for ... although calibre should REALLY not be doing this so someone should report this to calibre as a bug. Please feel free to link to this issue if you need to.

@dteviot Yeah fun.

Also i might be away for a few days because of joining the navy (for several reasons) But i'll do my best to keep up with stuff.

I suggest possibly making an option in #14 for this instead of doing it by default.

You may want to add OS and Calibre version.

The bug is said to have been fixed last week: https://bugs.launchpad.net/calibre/+bug/1598465

I've checked out the latest version 2.62.0 and it seems to have no problem with three dots. Good, good.

@dteviot @dreamer2908 awesome

If there are no further issues i'm going to close this for now since calibre no longer seems to have this issue.

If you need this issue reopened then just @ me in a comment on this issue and i will reopen it.
