问题 I am facing a problem that I am sure is pretty common. I found many solutions to this problem, and they all have their pros and cons. I'll post what I found here (which I believe will be useful to others), and I hope you'll point me in the right direction.

问题 I'm trying to format various coordinates in degrees/minutes and degrees/minutes/seconds prior to passing through measurements::conv_unit(), which requires the input as numbers separated by spaces. I've read various answers to similar questions, such as this one: Remove all special characters from a string in R? Which lead me to initially try: library(tidyverse) latitude <- "-36°48′31.33" str_replace_all(string = latitude, pattern = c("°|'|\"|′|″"), repl = " ") However, the prime symbol (′) is
