Find and Replace dialog cannot match text with multiple spaces

[Zoltan Koszegi]

Steps To Recreate (tested with IE9 on Demo page):

1) Include multiple spaces between words.

2) Click the 'Replace' tool.

3) Choose to replace " " with " " (or just find any number of spaces > 1).

RESULT: You can not find/replace 2 or more spaces.

This is probably because multiple spaces in html are represented as nbsp entities or binary nbsp characters plus a single space character, and probably CK doesn't handle that.

Problem can be reproduced from CKEditor 3.0 in both CKE 3.x and 4.x.

Another (similar) TC: the nbsp replacement sometimes goes a little wrong. Might be rare and/or impossible to fix but at least people coming from Google might find interesting: accidental double spaces can cause the content searchability to fail. To duplicate in IE9 or Chrome:

1. Go to ​http://ckeditor.com/demo
2. Clear the editor
3. Write "ponies rule" (with two spaces between the words)

CKEDITOR.instances.editor1.getData(); now returns "<p>ponies&nbsp; rule</p>".

4. Move caret to "ponies |rule" (caret after the two spaces)
5. Hit backspace to remove the 'accidental' double space

CKEDITOR.instances.editor1.getData(); now returns "<p>ponies&nbsp;rule</p>".

After step 5 the search function can't find "ponies rule". Happens even when entitites = false; in the config. Weather the first or second space gets entityfied seems to depend on the browser or luck.

I have tested this and Chrome in fact return "<p>ponies &nbsp;rule</p>" which after removing one space gets changed to "<p>ponies rule</p>". The first text with entity can't be found while second can.
This " &nbsp;" is controlled by browser and we can do nothing here but I believe editor should be able to search for entities to.

In IE this looks a little bit different. The "<p>ponies&nbsp; rule</p>" is created and search success fail depends on which space you remove (unlike in Chrome where always entity is removed). Anyway result is the same - of you have text with entity, it won't be found.

In Chrome, did you backspace the " " or the "nbsp"? Because for chrome for me actually does happen, see attached screenshot. Chrome Version "28.0.1500.72 m" on Windows 7 64bit. So in Chrome the TC is a little different, in step 4 the issue is duplicated by moving caret to "ponies | rule" and pressing backspace or "ponies| rule" and pressing delete.

I can't put the image directly here because Akismet tells me it's spam - derp!

We use CK editor in IE browser control. Everything I reported just tried with IE.

The bug with Find can also be reproduced in FF:

Steps:

1. Type in A B(with 2/3 spaces between the letters)
2. Open Find dialog and search for A B(with 2/3 spaces between the letters)

Result: Text was not found

It's a browser independent bug, and easiest use case is:

1. Open editor with following content: "<p>hello&nbsp;world</p>"
2. Open "Find" dialog box by clicking appropiate button on toolbar
3. Try to find sentence "hello world"

Actual result: Nothing found but should one
