Possible to concatenate escape sequence to string?

[Lcubed]

I would like to allow the user to enter a numerical code, that I
change into hex and concatenate it to \x to print out that character.

Something like this
String str = "\x" + hexstr;
But if I do the above, then I get an "Unrecognized escape sequence"
error.

Anyone know how to accomplish this?
Thanks!

The escape sequence is a compile-time thing.

If you want the user to enter the numeric code for a UTF-16 character and
convert that to a string in your code, just cast the integer value to
"char" and use it directly.

If you want to handle numeric codes for other encodings, you'll have to
convert the numeric code to the byte sequence it represents in that
particular encoding, and then decode those bytes (using, for example, the
Encoding class) to the equivalent string.

After a bit of experimentation, it works like I needed it to!
Thanks!

Just do
String str = @"\x" + hexstr;
