Greetings, I am using AUCTeX for typesetting mathematics in English and Polish language.
When I interactively call #'reftex-label and put space inside the label or an character commonly used in polish like ą ę ł ó ź ć ż I get message that it contains invalid characters. However, I successfully use the labels with spaces or utf8 characters without an issue. I am tempted to remove the aforementioned check for label characters domain. Why shouldn't I do that?
