regex - Remove all diacritics without script with a single formula for use in all cells without making calls to Google API

Question

I created a formula that removes diacritics but needs to make calls through an ImportDATA. If I use this formula on every cell I need, it will exceed the call limit I can make. And it will lock the spreadsheet.

=ArrayFormula(if(exact(A1,Upper(A1)),Upper(VLOOKUP(A1,split(trim(transpose(split(query(SUBSTITUTE(regexreplace(regexreplace(query(IMPORTDATA("https://docs.oracle.com/cd/E29584_01/webhelp/mdex_basicDev/src/rbdv_chars_mapping.html"),"Select Col1 where Col1 contains '<td'",),"<td class=.+>","")&"~"&MOD(ROW(A:A),4),".+~[01]$",""),"~3","@"),"",9^6),"@"))),"~2"),2,0)),split(trim(transpose(split(query(SUBSTITUTE(regexreplace(regexreplace(query(IMPORTDATA("https://docs.oracle.com/cd/E29584_01/webhelp/mdex_basicDev/src/rbdv_chars_mapping.html"),"Select Col1 where Col1 contains '<td'",),"<td class=.+>","")&"~"&MOD(ROW(A:A),4),".+~[01]$",""),"~3","@"),"",9^6),"@"))),"~2")))

Instead of making this call to ImportDATA, I would like to use column A to put the diacritics and column B the corresponding common letters ... So make changes without having to make calls outside the spreadsheet and also without having to of creating a new Script function that is also often used, has a google limit that blocks usage ... But as I created this formula with the help of 3 answers here from StackOverflow, now to make this change I'm not succeeding.

And preferably that this formula already made the changes in a complete column instead of converting one cell only.

=ARRAYFORMULA(PROPER(IFERROR(REGEXREPLACE(L2:L, TEXTJOIN("|", 1, J2:J),
 VLOOKUP(REGEXEXTRACT(L2:L, TEXTJOIN("|", 1, J2:J)), J2:K, 2*
 SIGN(ROW(A2:A)), 0)&""), L2:L)))
