or it's better to get by with multiple parameters because in the "decode" procedure
it is necessary to iterate with a space and it is better to adhere to the same style of calling functions

Hello,
I have to find out whether the last character is digit or alphabet. I manage to strip the last character but would need some help if there is one liner available to test the above.

base64
base64(n) Text encoding & decoding binary data base64(n)
__________________________________________________________________________________________________________________________________________________NAME
base64 - base64-encode/decode binary data
SYNOPSIS
package require Tcl 8
package require base64 ?2.4.2?
::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
::base64::decode string
_________________________________________________________________DESCRIPTION
This package provides procedures to encode binary data into base64 and back.
::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
Base64 encodes the given binary string and returns the encoded result. Inserts the character wrapchar every maxlen characters of
output. wrapchar defaults to newline. maxlen defaults to 76.
Note well: If your string is not simple ascii you should fix the string encoding before doing base64 encoding. See the examples.
The command will throw an error for negative values of maxlen, or if maxlen is not an integer number.
::base64::decode string
Base64 decodes the given string and returns the binary data. The decoder ignores whitespace in the string.
EXAMPLES
% base64::encode "Hello, world"
SGVsbG8sIHdvcmxk
% base64::encode [string repeat xyz 20]
eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
eHl6eHl6eHl6
% base64::encode -wrapchar "" [string repeat xyz 20]
eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
# NOTE: base64 encodes BINARY strings.
% set chemical [encoding convertto utf-8 "Cu2088Hu2081u2080Nu2084Ou2082"]
