Internet standards such as RFC 3986 on URI syntax explicitly state that diacritics should not be used in links. It is recommended that URLs contain only basic alphanumeric characters (A-Z, a-z, 0-9) and some special characters such as '-', '_', '~' and '.'. This allows for compatibility and consistency between different systems and platforms. URLs with accented characters may be difficult for some users to read and understand. Especially people who are not proficient in a given language may have problems entering and recognizing such addresses. This can lead to errors and confusion. It is worth noting that while diacritics are not recommended in URLs, some browsers and operating systems may automatically replace some diacritics with their ASCII equivalent (e.g. "ł" becomes "l"). Nevertheless, for consistency and compatibility, it is recommended to avoid diacritical marks in links and use simple, readable URLs. Amen
