Functions
int64_t	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 >	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 >	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 >	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	encode (int num, const alphabet &aspec, const unsigned int min_width=0) noexcept
	Encodes a given positive decimal number to a symbolic string representing a given alphabet and its base.
std::string	encode (int64_t num, const alphabet &aspec, const unsigned int min_width=0) noexcept
	Encodes a given positive decimal number to a symbolic string representing a given alphabet and its base.
std::string	encode64 (const void *in_octets, size_t in_len, const alphabet &aspec) noexcept
	Encodes given octets using the given alphabet and fixed base 64 encoding according to base64 RFC 4648.
std::string	encode64_mime (const void *in_octets, size_t in_len, const alphabet &aspec) noexcept
	Encodes given octets using the given alphabet and fixed base 64 encoding according to base64 RFC 4648 and adds line-feeds every 76 characters as required for MIME.
std::string	encode64_pem (const void *in_octets, size_t in_len, const alphabet &aspec) noexcept
	Encodes given octets using the given alphabet and fixed base 64 encoding according to base64 RFC 4648 and adds line-feeds every 64 characters as required for PEM.
size_t	insert_lf (std::string &str, const size_t period) noexcept
	Inserts a line feed (LF) character \n (ASCII 0x0a) after every period of characters.
bool	operator!= (const alphabet &lhs, const alphabet &rhs) noexcept
bool	operator== (const alphabet &lhs, const alphabet &rhs) noexcept
size_t	remove_lf (std::string &str) noexcept
	Removes line feed character from str.
std::string	to_string (const alphabet &v) noexcept

Base codecs, i.e.

changing the decimal or binary values' base for a different representation.
