Shell Bash equivalent to python ""?

If an equivalent in iconv exists I don't know which is the right one. Wanted instead of "L" as issue "LATIN CAPITAL LETTER L".
Didn't want a python oneliner because it to execute as bash script through an external file or panel starter gets it more complicated with additional special characters and quotes.
Thanks for help

import unicodedata; print ("L"))

echo -e "L" | iconv -f UTF-8 -t UNICODELITTLE//TRANSLIT
Thanks, have too found the two files on the system. Exist there execute commands for the files?
zcat /usr/share/i18n/charmaps/UTF-8.gz
cat /usr/share/X11/locale/en_US.UTF-8/Compose
