195946 - Form controls convert NBSP to SP

Status: VERIFIED DUPLICATE of bug 218277

(Core :: Layout: Form Controls, defect)

Description

[sewellpm]

User-Agent:       Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.4a) Gecko/20030304
Build Identifier: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.4a) Gecko/20030304

When a non-breaking space character (NBSP, 0xa0) is entered into a form control,
it is converted into a normal space (SP, 0x20).  

Because of this, a legal JavaScript string can change value when it is pasted
into a form for analysis.

This behavior was not present in Mozilla 4.

Reproducible: Always

Steps to Reproduce:
1.  Load this sample HTML:

<form onsubmit="return false">
<input name="Source" size="20" value="keep&nbsp;together">
<input type="submit" onclick="Target.value=escape(Source.value)">
<input name="Target" size="20">
</form>

2.  Press the button.  The Target text control displays a URL-encoded copy of
the Source control.
Actual Results:  
Target reads "keep%20together".

Expected Results:  
Target should read "keep%A0together".

Confirmed using http://www.squarefree.com/htmledit/ in Firebird 07/23.  Also
happens with   in place of  .  Also happens if you copy the nbsp out
of the form.  (But ctrl+left / ctrl+right shows that the text in the form has a
non-breaking space.)

This seems to be the same problem as bug 218277 which is being resolved with a
patch.

Bug confirmed with Firebird 0.7+ 20031106

I tested with my own Mozilla version with the patch I submitted for bug 218277
It worked fine then. I got keep%A0together. So bug 195946 and bug 218277 will be
both resolved with the patch (id=136358).
