Title: Character corruption upon inline edit after 2.0.16 update
Post by: spiros on December 31, 2019, 06:13:55 AM
When using inline edit on topic level, I get non-ASCII character conversion in subject and body text to Unicode Character Names. It happens with all tested themes. It also happens in a vanilla forum just after installing 2.0.16

Hello everyone!!!
I confirm that after updating to 2.0.17 there was a problem with encoding. utf8
How do I disable this feature?

I had to remove the inline edit button in the theme template.

Hi!!! How did you delete this button? In what file and what line???

Depends on your theme. For example in default theme, Display.template.php, remove this

Code: [Select]
// Can the user modify the contents of this post?  Show the modify inline image.
if ($message['can_modify'])
echo '
<img src="', $settings['images_url'], '/icons/modify_inline.gif" alt="', $txt['modify_msg'], '" title="', $txt['modify_msg'], '" class="modifybutton" id="modify_button_', $message['id'], '" style="cursor: ', ($context['browser']['is_ie5'] || $context['browser']['is_ie5.5'] ? 'hand' : 'pointer'), '; display: none;" onclick="oQuickModify.modifyMsg(\'', $message['id'], '\')" />';

Just leave script.js from 2.0.15 version. For me after that inline edit works well again.

Pretty sure that will re-introduce two separate bugs - the multi-byte preview problem, and the Firefox code select bug.

I can't confirm it has returned, but I think it's much lesser evil than destructive consequences of that unpleasant behavior for Cyrillic world.

Absolutely.
It is difficult for someone who runs Latin-character-based forums to appreciate the destructiveness of this bug  :)

What errors do you write about if users edit their posts and this will kill all the forums?
It is like a terrorist attack.

Indeed, pretty minor (and not affecting the text output) compared to this.

In my forum https://wotcheats.ru (Russian lang) this FIX work very well.
Change script.js
Code: [Select]
// Convert a string to an 8 bit representation (like in PHP).
String.prototype.php_to8bit = function ()
{
if (smf_charset == 'UTF-8')
{
return this;
}
















else if (this.oCharsetConversion.from.length == 0)


TO

Code: [Select]
// Convert a string to an 8 bit representation (like in PHP).
String.prototype.php_to8bit = function ()
{
if (smf_charset == 'UTF-8')
{
var n, sReturn = '';

for (var i = 0, iTextLen = this.length; i < iTextLen; i++)
{
n = this.charCodeAt(i);
if (n < 128)
sReturn += String.fromCharCode(n)
else if (n < 2048)
sReturn += String.fromCharCode(192 | n >> 6) + String.fromCharCode(128 | n & 63);
else if (n < 65536)
sReturn += String.fromCharCode(224 | n >> 12) + String.fromCharCode(128 | n >> 6 & 63) + String.fromCharCode(128 | n & 63);
else
sReturn += String.fromCharCode(240 | n >> 18) + String.fromCharCode(128 | n >> 12 & 63) + String.fromCharCode(128 | n >> 6 & 63) + String.fromCharCode(128 | n & 63);
}

return sReturn;

}
else if (this.oCharsetConversion.from.length == 0)

This issue is tracked in the internal log as #123/PR#124 & will target 2.0.18.

Any changes you make must be reversed before you apply 2.0.18. 

The changes I would recommend to script.js are:

Find this:
Code: [Select]
if (smf_charset == 'UTF-8')
{
return this;
}

Replace with:
Code: [Select]
if (smf_charset == 'UTF-8')
{
var n, sReturn = '';

// Recode from UTF16 (native .js) to UTF8
for (var i = 0, iTextLen = this.length; i < iTextLen; i++)
{
// Below xFFFF, UTF16 simply = the code points
n = this.charCodeAt(i);
if (n < 128)
sReturn += String.fromCharCode(n);
else if (n < 2048)
sReturn += String.fromCharCode(192 | n >> 6) + String.fromCharCode(128 | n & 63);
// 0xD800 - 0xDBFF
else if (n >= 55296 && n <= 56319)
{
// In this range, this is the beginning of a surrogate pair, where 4-byte utf8 chars are
n = 65536 + ((n & 1023) << 10) + (this.charCodeAt(i + 1) & 1023);
sReturn += String.fromCharCode(240 | n >> 18) + String.fromCharCode(128 | n >> 12 & 63) + String.fromCharCode(128 | n >> 6 & 63) + String.fromCharCode(128 | n & 63);
// Skip next char, already used...
i++;
}
else
sReturn += String.fromCharCode(224 | n >> 12) + String.fromCharCode(128 | n >> 6 & 63) + String.fromCharCode(128 | n & 63);
}

return sReturn;
}

And also find this:
Code: [Select]
String.prototype.php_urlencode = function()
{
if (smf_charset == 'UTF-8')
return encodeURIComponent(this);

return escape(this).replace(/\+/g, '%2b').replace('*', '%2a').replace('/', '%2f').replace('@', '%40');
}

Replace with:
Code: [Select]
String.prototype.php_urlencode = function()
{
return escape(this).replace(/\+/g, '%2b').replace('*', '%2a').replace('/', '%2f').replace('@', '%40');
}

I believe this will address all of the issues.

This fix doesn't work for me :(
I am using Bulgarian language (Bulgarian UTF-8 language pack). I have removed 'Modify' button from post body and problem disappeared.
