How can I insert a line break before a specific character?

[nicewillsuccess]

I want to insert a line break before a specific character. I considered using '\n' before the character, but it affects the style and is quite complex to handle. I noticed that in the documentation for text editors, only the run object can add line breaks, but it cannot be inserted before a specific character. Is there a better solution?
