It is said: "Identifiers must start with a letter, the currency digit and conecting characters such as _ Underscore"

What other conecting characters apart from "_" can be used in identifiers?

I can't see any other

Java Spec says:
The Java letters include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access preexisting names on legacy systems.
