text = "\u2654"; // [\u2654:white king, \u2655:white queen]
text = "\u2654"; // [\\u2654:white king, \\u2655:white queen]

result

Oops, test it first! //suite a=1;// [0:♔king,1:♔queen] echo(a);

[sugizo]

perhaps not getting what my objective is

objective is to create the drop down combo list
when user change it, let say 'white king'
then it will change the variable text, that will show the unicode white king in openscad

this work but when turn it into variable is not work
text("\u2654", size = 10, font = "Caslon");

not work

chess_text = "\u2654"; // ["\u2654":white king, "\u2655":white queen]

text(chess_text, size = 10, font = "Caslon");

perhaps openscad repo can activated the github discussion feature

Seems escaping doesn't work either .. it is not converted in a symbol anymore.

chess_text = "\u2654"; // ["\u2654", "\\u2655"]


echo("\u2654",chess_text);
text(chess_text, size = 10, font = "Caslon");
text("\u2654", size = 10, font = "Caslon");

NO. GitHub is for Development purposes including bug reports, and only for matters which cannot be solved by the Mailing-list.
It is not to teach people how to code in OpenSCAD.

There are people on the Mailing-list, including many Developers, who can help you there.

Escaping is a property of STRINGS, ie part of statements or expressions.
Anything after // is UTF text, it is ignored by the main parser, and only text is used by customizer, not strings.
So anything special-UTF in comments just need to be pasted in as UTF characters/symbols/glyphs.

//suite
a=1;// [0:♔king,1:♕queen]
chesstext = (a==0) ? "\u2654" : "\u2655";
echo(a,chesstext);

ECHO: 0, "♔"

[MichaelAtOz]

BTW, Customizer has external syntax dependencies with Thingiverse.
Any changes would need to be carefully considered, so using techniques like above is currently best practice.

[UBaer21]

textFix = 9812; // [9812:"♔", "♕"]
echo(chr(textFix),ord(chr(textFix)));

text(is_num(textFix)?chr(textFix):textFix, size = 10, font = "Caslon");

[UBaer21]

Anything after // is UTF text, it is ignored by the main parser, and only text is used by customizer, not strings.

@MichaelAtOz But there is some parsing done by the customizer as some are converted to strings and as the escaping does produce the same echo. Or why is the "\" removed also "" are added for text if if not there but not for numbers. I can understand that this is bit confusing. But text is also not displayed with »"« which makes [1,"1"] look equal in the dropdown box , And as far as i can see it is not documented.

cust=1;//[a,1,"1",""1""]
echo(cust);

[sugizo]

code work

text = "♔"; // [♔:King, ♕:Queen, ♖:Rook, ♗:Bishop, ♘:Knight, ♙:Pawn, ♚:king, ♛:queen, ♜:rook, ♝:bishop, ♞:knight, ♟:pawn]
font_family = "Caslon"; // [Caslon, Chrysanthi Unicode, DejaVu Sans, DejaVu Sans Mono, FreeSerif, MV Latin, Pecita, Quivira, Scid Chess Traveller, Symbola]

problem
it's just the font family, if already read the unicode, don't bother using 'code point' just copas the 'symbol' will solve the problem
