OPF manifest item href with percent-encoded URL results in filepath failure

[gregoriopellegrino]

Please provide the following details if possible or relevant:

• Ace GUI 1.0.0-rc.1
• macOS 10.14.5

I downloaded an EPUB 2, launched the DAISY app, selected it for checking, but I get no results.

In the log I see:

Running Ace on /Users/uu/Downloads/Test ebook.epub
[object Object]

I can send you the file privately.

Thank you for the report!
Do you get the same result with Ace CLI?

[danielweck]

PS: I moved this issue to the Ace GUI repository, as per your issue description.

Could you please share (privately) the EPUB file with me daniel.weck@gmail.com
Thanks!

On Ace CLI I get

info:    Processing /Users/uu/Downloads/Test ebook.epub
info:    Parsing EPUB
error:   Failed to parse EPUB
error:   Unexpected error: ENOENT: no such file or directory, open '/var/folders/p3/k6l3_3qn7sjdlzshshj4dg2h0000gn/T/tmp-1126u0hnbQ4MurYI/OEBPS/Senza%20titolo-1.xhtml'

Immediately I see that the space character in the filename is escaped for URL usage (%20), so perhaps this is the cause.

[gregoriopellegrino]

I think the same, but it is possible in EPUBs, is it?

The EPUBcheck reports warnings about filenames with spaces, but no errors.

I am able to reproduce this bug in the latest "beta" Ace CLI ( https://www.npmjs.com/package/@daisy/ace/v/1.2.0-beta.4 ) from this PR / branch #236
This is definitely an issue related to URL escaping / percent-encoding. I am looking into it.

[danielweck]

The latest "beta" version (1.2.0-beta.4) of Ace includes a fix for this issue (i.e. proper handling of URL percent-encoding and HTML URL escaping on all ZIP resources, including support for non-ASCII chars in file names).

@gregoriopellegrino I tested the fix with your publication Zenaro esercitazione ebook.epub
You may try this yourself by installing Ace "beta" from the next NPM release channel:
npm install --global @daisy/ace@next (alternatively, you may remove --global to install the Ace packages locally, inside a folder-contained NPM project)

Notes to developers:
https://www.npmjs.com/package/@daisy/ace/v/1.2.0-beta.4
... is built from the codebase in this PR / branch #236

It works great, thanks!
