Normalizer.normalize cannot smooth "Ł"

Question

I need to smooth out the emphasis. I found some solutions

Normalizer.normalize(txt, Normalizer.Form.NFD).replaceAll( "\\p{IsM}+", "") 

OR

 Normalizer.normalize(txt, Normalizer.Form.NFD).replaceAll( "[^\\p{ASCII}]", "") 

The first p{IsM} smooths the very accent

 ążł Tĥïŝ ĩš â fůňķŷ Šťŕĭńġ ĄĆĘŁŃÓŚŹŻ 

to

 azł This is a funky String ACEŁNOSZZ 

but this method cannot change "Ł" to "L"

second "p{ASCII}" delete "Ł" az This is a funky String ACENOSZZ but I need azl This is a funky String ACELNOSZZ

I found more patterns, for example p {M} or p {InCombiningDiacriticalMarks} but it doesn’t work. When I look for a solution, some people will comment on this situation, such as smoothing a letter is not possible.

Who can help me find a solution? but if possible, I don't want to manually replace each letter

thanks for the help
