Short utility functions to clean certain characteristics of strings. These are combined in string_clean.

.remove_special_chars(string)

.replace_umlaute(string)

.remove_diacritics(string)

string

A character vector.

Replace any characters that do not belong to Regex classes \w or \d, or are a literal whitespace, by a single whitespace. The function preserves German Umlaute and diacritical letters.

Elaboration on the Regex classes: https://stackoverflow.com/a/2998550/13542638.

Replace German Umlaute by their ASCII representations: "ä"->"ae", "ö"->"oe", and "ü"->"ue". "ß" is diacritical and handled by .remove_diacritics.

Replace diacritical letters(é, ç, ...) with their "plain" versions. This function can only handle diacritical letters from latin-based alphabets. Elements in string containinig non-latin letters (e.g. cyrillic), will be replaced by NA and a warning will be given.

Reference: https://stackoverflow.com/a/20495866/13542638

.remove_special_chars returns string with non-letter Unicode characters replaced by a whitespace.
