 Is there a way to display strikethrough text on an interface? I would like to display deleted text with strikethrough when compared two strings. I appreciate any response to this quesiton. 
 Thanks,

I came up with this neat solution. 
 a!localVariables(
 local!string: "This is my strike through test",
 joinarray(
 a!forEach(
 items: enumerate(len(local!string)),
 expression: charat(local!string, fv!index) & char(822)
 ),
 ""
 )
)

I have no samples, but here is the design I would follow: 
 
 Create a constant that has the mapping in key format 
 Create expression rule findStrikeThroughChar that takes in one ri!charIn that returns the single character strike through character
 
 Here you will use the constant above and the keyval function to replace one character at a time 
 docs.appian.com/.../fnc_text_keyval.html

Create expression rule replaceStrikeThroughText having one ri!textIn that returns the translated strike through text
 
 Call the findStrikeThroughChar for every char in the string to replace each char position 
 Use a!forEach with len and charat

First add Redline plug-in, then use the below code in UIT in Appian.

a!localVariables( local!existingText_txt: "My name is Koushal", local!newText_txt: "My friend is Koushal", local!comapreTextCode: comparetext( local!existingText_txt, local!newText_txt ), a!richTextDisplayField( value: a!forEach( items: local!comapreTextCode, expression: a!match( value: fv!item.operation, equals: "Add", then: a!richTextItem( color: rule!IP_utils_getColors("green"), text: " " & fv!item.value ), equals: "Delete", then: a!richTextItem( color: rule!IP_utils_getColors("red"), text: fv!item.value ), equals: "Same", then: a!richTextItem( color: rule!IP_utils_getColors("black"), text: fv!item.value ), default: a!richTextItem(text: "") ) ) ) )
