Bug: TinyMCE add unwanted no-break-space in text

[Daijobou]

This behavior looks complete random. I can't repoduce it.

I don't know how this happen and why, the button "Show invisible characters" show me since 4.x very often random protected space-cahracters (no-break) in my text and prevent often correct line breaks. I have type this text and never ever add this spaces. How I can prevent tinymce from insert random no-break characters?

have you tried entity encoding and set it to raw ?

I use raw in entity_encoding :)

Can anybody confirm this? You can check this with "Show invisible characters"-button.

I found this https://ckmacleod.com/2017/03/23/exterminating-non-breaking-space-bug/

In short, when the user, operating in a certain common way, replaces selected text with new text, an adjacent white space gets converted into a non-breaking space or facsimile, which can disrupt word-wrapping, since the non-breaking space is, perhaps unsurprisingly, a space that does not break: The affected browser treats the   as a single letter within a single, not to be broken word.

Note that the bug does not recur during many common types of revision, but mainly during a peculiar type of text highlighting and replacement: The typical writer behavior that produces the problem is, to be more precise, a kind of confined over-writing (in the operational, not the stylistic sense), not usually simple deletion and replacement. Note also that it occurs only while working in the “Visual” editor (the preference of, I believe, the vast majority of WordPress users).

I don't use wordpress or other CMS.

Its allowed to highlight? @fyrkant maybe you can help with this topic? :)

Really this issue destroy so often the text flow and make stupid looking lines. Problem is here, I can't remove this non-breaking spaces with backspace, its coming back again. Actual I have a outside button to remove non-breaking spaces in the whole text. But thats not a nice solution.

Here a video (webkit browser)

Here the fiddle

I not insert non-breaking spaces by my self. Its the editor/browser.

After years of this issue I would really like a solution for this, like a option in the settings. It should be possible to detect/check when a single non-breaking space is not surrounded by (non-breaking)spaces. Its only must then replace(/\u00A0/g, ' ') back to a normal space. So caret positon not change.

Okay
X[single-non-breaking-space][single-non-breaking-space]X
X[SPACE][single-non-breaking-space]X
X[single-non-breaking-space][SPACE]X

Not Okay
X[single-non-breaking-space]X

funfact: make slow space and a character its replace space with non-breaking space, but make fast space and character, its do it not. See here:

@Daijobou I can confirm this problem. It looks the same for me. The nonbreaking space is occuring only in chrome after waiting a fiew seconds after hitting the space bar and wait. If i write right along, there is no &bnsp;. I use the plugin visualchars.

Is there any progress in this issue?

@Afraithe sorry to ping you directly but I noticed you seem to check bugs. Can you please test this one? We have a social network script and our clients are experiencing this issue on their sites. Would be super cool to have a fix. :)
