Functions
int64_t	jau::codec::base::decode (const std::string_view &str, const alphabet &aspec) noexcept
	Decodes a given symbolic string representing a given alphabet and its base to a positive decimal number.
std::vector< uint8_t >	jau::codec::base::decode64 (const std::string_view &str, const alphabet &aspec) noexcept
	Decodes a given symbolic string representing using given alphabet and fixed base 64 to octets according to base64 RFC 4648.
std::vector< uint8_t >	jau::codec::base::decode64_lf (const std::string_view &str, const alphabet &aspec) noexcept
	Decodes a given symbolic string representing using given alphabet and fixed base 64 to octets according to base64 RFC 4648 and removes all linefeeds before decoding as required for PEM and MIME.
std::vector< uint8_t >	jau::codec::base::decode64_lf (std::string &str, const alphabet &aspec) noexcept
	Decodes a given symbolic string representing using given alphabet and fixed base 64 to octets according to base64 RFC 4648 and removes all linefeeds before decoding as required for PEM and MIME.
std::string	jau::codec::base::encode (int num, const alphabet &aspec, const unsigned int min_width=0) noexcept
