qdapRegex::rm_nchar_words returns different results when non English letters involved?

Please help me with the following confusion:

qdapRegex::rm_nchar_words("è ûé", "1,2") [1] "è ûé"

qdapRegex::rm_nchar_words('k ku ppp d', "1,2") [1] "ppp" Why in the first code line it doesn't respond with "" but in the second one it works as expected. What do I miss here? The only thing I can think that in the first line of code the string is built from non English letters.

Any solution?

It uses \w to define letters which is defined as [A-Za-z0-9_]. You would need to write your own custom regex to handle the non-ascii letters

@trinker but you may observe that it works for others in the above stackoverflow question (akrun says it works for him).
