When a label is to be dynamically read from the active screen based on the active DynamicText setting for the label, it may contain extra characters on the physical screen that are unwanted in your web page. For example, while on a screen the colon (:) may be used to differentiate the label, on your web page responsive design label styling and position achieve this and the colon may be considered inappropriate.
To strip any unwanted characters from labels on this screen when DynamicText is true for a label, include the characters in this property.
Default: . : (Period, Space and Colon characters are stripped from labels)
