Converting Unicode characters

[bellecombe]

Hi
In my tcl script I have this: [pre]...
append p "B,confirmButton,\u2714,,Exit Ok;"
...[/pre]
that is used for generate a form button with caption the Unicode Lower Right Pencil.
When this is into a file this not appens i.e I am not be able to convert the below alternatives into a
desired caption.
[pre]
B,execButton,✎,,tryForm;
B,execButton,\u270E;[/pre]
The file is coded utf8 without BOM.

1) Do you want utf8 or utf16 type unicode?
2) Are you writing to a file or do you want it displayed in a GUI or a console
3) Are you using Linux or Windows

Thanks xwb
The file is coded utf8 without BOM; I am working on Windows and in my application I have both a TCL variable both a file text that contains \u270E and the first case Lower Right Pencil is showed correctly.
For the \u270E in a file I have found an answer i.e.:
[pre]...
if {[file exists $params] == 1} {
set fp [open $params r]
set params [fg_Unicode [read $fp]]
close $fp
}
...
proc fg_Unicode {s} {
set RE {[][{}\u0100-\uffff]}
set substitution {[format \\\\u%04x [scan "\\&" %c]]}
return [subst [regsub -all $RE $s $substitution]]
}[/pre]
