Abstract

chimchar stands for CHanging IMpractical CHARacters. It modifies characters in string variables that are unfriendly to functions like destring and reclink. In particular, it can replace special characters that are based on Latin letters with their closest plain Latin letter counterpart(s); for example, "Æ", "š" and "ĸ" become "ae", "s", and "k", respectively. You can choose to change special characters, fix special characters and remove numeric characters, or remove all non-numeric characters altogether.
