Unexpected error invalid high surrogate character(0xDF4C).A high surrogate character must have a value from range(0xD800-0xDBFF) during read stage in java based application

[Kiranmaivasamse]

We are getting this error when we are trying to read a value from an element in a java based application "A high surrogate character must have a value from range(0xD800-0xDBFF) during read " Because of this error some of our processes are getting terminated by throwing unexpected stack empty error. Is there any work around to handle this issue in Blueprism?

The high surrogate error typically happens when a String Data Item is not in a valid format. (the fields being spied might have control characters which might not be visible), maybe open a ticket with support if its handled in a future version.

finally, i got it fixed with lucky, 
when i spy oracle form : [queue] field, attribute JAVA TEXT with invalid characters spied, even i didn't check this attribute. 
then i just delete those characters and keep its value blank, it fixed. ever warning surrogate % issue.
wow!

I was also facing similar kind of issue where I was reading java label where blue prism was getting failed due to invalid high surrogate character.
I have come up with a workaround which worked for me which is nothing but I have added Navigation action to focus the text which ideally selected my target text and then I read the text using Get Selected Text which gave me proper output.

So Idea behind reading the text is select the text and then read instead using Get Text.
