Parts of text existing, but not shown

MaxM · 10-29-2018, 10:57 AM

Hi everybody,

I'm on Win 10, Eval. 18234.

I converted a pdf using Calibre. In the editor it's looking like this:

Click image for larger version

Name: c2.PNG
Views: 275
Size: 172.7 KB
ID: 167282

Why can't I see this stuff?

The Calibre Viewer shows it like:

Click image for larger version

The stylesheet looks like:

.calibre {
display: block;
font-size: 1em;
padding-left: 0;
padding-right: 0;
margin: 0 5pt
}
.calibre1 {
display: block;
margin: 1em 0
}

Why is the viewer showing text on top of each other?

Thanks everyone.

Regards,
Max

If the code screen capture is full left margin
The HTML tags are severely mangled.

Code:

<p class="indent">Below him,

NOT
[edited]

Code:

<p
class="indent"> Below him,

I don't believe a tag can have a newline

This line:

had multiple double blanks between each word.

After I replaced these:

it looked quite normal.

Good to know.

[Edit]
Not only that, but I recognised that the Pdf-converter used (hex) "a0" istead of (hex) "20" for blanks.

Thanks,
Max

Interesting that it used a non-breaking space rather than a standard space.

that would account for the visual mess in the tags between the tag and attribute. all the rest is being treated as an unbroken line

Newlines shouldn't be a problem. The HTML spec says that whitespace is ignored inside tags (section 8.1.2 in the current version of the spec).

We all KNOW how well ADE follows "the spec"

BTW e-books follow a subset of HTML, not the full thing

Old adage:
"If it hurts when you do this...
Stop doing that!"

There is "the spec", and then there is reality.
My K4 refuses to show some books as they appear in: K4PC, The Kindle Previewer and Calibre's book viewer. (and the code does not trip warnings)

It's the adjacent non-breaking spaces which cause this problem of some text being invisible in the Editor - usually around the line wrap area. I see it quite often.

I have a vague memory, from a while ago, that it's a known problem with the underlying Qt library, i.e. not fixable by calibre alone.

↑ ↑ ↑ - likewise.

It's one of the reasons why I use Sigil for editing the code.
