I have a file containing many vowels with diacritics. I need to make these replacements:

  • Replace ā, á, ǎ, and à with a.
  • Replace ē, é, ě, and è with e.
  • Replace ī, í, ǐ, and ì with i.
  • Replace ō, ó, ǒ, and ò with o.
  • Replace ū, ú, ǔ, and ù with u.
  • Replace ǖ, ǘ, ǚ, and ǜ with ü.
  • Replace Ā, Á, Ǎ, and À with A.
  • Replace Ē, É, Ě, and È with E.
  • Replace Ī, Í, Ǐ, and Ì with I.
  • Replace Ō, Ó, Ǒ, and Ò with O.
  • Replace Ū, Ú, Ǔ, and Ù with U.
  • Replace Ǖ, Ǘ, Ǚ, and Ǜ with Ü.

I know I can replace them one at a time with this:

sed -i 's/ā/a/g' ./file.txt

Is there a more efficient way to replace all of these?

bash sed replace
