Constants

const (
	DigitsAndEnglish = `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz`
	DigitsAndSwedish = `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZÅÄÖabcdefghijklmnopqrstuvwxyzåäö`
	DigitsAndGerman  = `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜẞabcdefghijklmnopqrstuvwxyzäöüß`
)

Keep in mind that some symbols take >1 byte and if used to generate random string, the result may not be human-readable.

åäö - this string, for example, takes 6 bytes, not 3. So if you try to take random bytes from here, you will possibly get something like `�å`
