get ICaret.DisplayCharacterColumn is higher than 9600

We are forced to wrap the line at a certain point even if word wrap is off because if WPF tries to render past a certain X location, it throws an exception.  The wrapping prevents that exception from occurring, and that is why this scenario happens. 

The column is being reported correctly in this scenario though.  Column is more of where the caret is visually, while Character tells you where the actual character is on the document line.

But there is another caret position with exactly same line and column no. (eg line = 12, column = 1. 1st character and 9601st character both characters have the same values of line and column)

The wrapped 3rd, 4th lines also have the same line and column values.

How shall I differeniate between these caret positions, which have same line and column values.

I need to get the correct column no. (eg: If wrapped as 2nd line, then 9600+1 = 9601)

Is there any way to get the column no?

The Column number is a visual X position based on the average character width.  Since the line is being wrapped here, a small column number is correct at the start of both the unwrapped and subsequent wrapped lines.  Word wrapped lines (when you have that feature enabled) behave the exact same way, and VS also shows Columns as we do where each wrapped line starts at column 1.

The Character number on the other hand designates the logical character position within the current document line.  A combination of those three values (Line, Column, Character) gives you a unique position, even in this scenario.  If you only show Line and Column alone, as you saw there will be duplicates in this scenario.
