I use 18.3 aspose version.
I need use function JoinRunsWithSameFormatting . But same runs have , and run near them doesn't. How can I remove from all runs of document. Thank you.
It is not actually clear what you need to achieve. but I suspect you need to clear formatting of all runs and then join them together. If so, you can use Font.ClearFormatting method to achieve this.
