Hi all

A user has rightly reported to me that multiple space characters get
stripped when saving my grid content to HTML in the following
scenario:

Content of Grid :
ABCDE.txt
A BCDE.txt
A  BCDE.txt
A   BCDE.txt

Content of HTML output :

ABCDE.txt (correct)
A BCDE.txt (correct)
A BCDE.txt (wrong)
A BCDE.txt (wrong)

The line where this occurs is when I write the content of my DBGrid. I
get the content like this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i MyString :=
DBGrid.DataSource.DataSet.Fields[1].AsString; 
And then I write it to the HTML stream like this :
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var  fs   
        : TFileStreamUTF8;begin  fs.Write(MyString[1],
Length(MyString));end; What might causing the multiple spaces to be
stripped?

Hi!

That is due to HTML specification:

Multiple spaces are reduced to one.

If you want to get a protected space you have to use

Code: HTML5  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
