Parsing special characters in strings to HMI

PLCnext Engineer

Hi,
I am using strings to store engineering unit information for values, but special characters are not showing correctly in the HMI.
Examples are:

* °C
* µ
The below screenshot shows the symbol rendered for degree centigrade.
Is this a limitation in the IEC-standard or in PLCnext Engineer’s parsing of character sets between PLC and HMI ?

You should use WSTRING datatype for this proposes.
Best regards.

From the above picture, I present the value and the unit in two different Text-symbols.
The value is a real, the value is a WSTRING.
Is it possible to combine these two into one Text-symbol? I have tried concat, but that only works for strings.

TO_WSTRING (with the required formatting) plus CONCAT should do it, I think.
TO_WSTRING ');\n mywindow.document.close(); \n mywindow.focus();\n setTimeout(function () {\n mywindow.print();\n mywindow.close();\n }, 1000)\n return true;\n}\r\n\r\n\r\n
