MNeto:
Thanks!

Because the character is UTF16, I modified your code and it worked (I'm using Qt):


--- Code: Pascal  [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---uses  LazUTF16;...var  s: string;...  s := UnicodeToUTF16($1D435);  Label1.Caption := s; 

JuhaManninen:
MNeto, "String" is UTF-8 in Lazarus by default. This:

--- Code: Pascal  [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---s := UnicodeToUTF16($1D435);does not make much sense. It only triggers extra automatic conversions.

Not true. Data between any Unicode encodings can be converted losslessly.

MNeto:
Really...
It works with UTF8 ...

Now I understand. I thought, incorrectly, unicode SMP could only be represented as UTF16.

Why SMP unicode characters behave differently from BMP unicode characters in Lazarus?

Thank you.

Uh? All Unicode codepoints can be represented in both UTF-16 and UTF-8.

U+1D435 MATHEMATICAL ITALIC CAPITAL B
UTF-8: 0xF0 0x9D 0x90 0xB5
UTF-16: 0xD835 0xDC35
XML decimal entity: &#119861;

Understand.

I had a wrong idea of the Unicode standard. Sorry, I am not an experienced programmer.

I thought the unicode value of a character was just a number in hexadecimal. I did not know their internal representation.
