Ty Agnius, i went to the python way , in case anyone needs it here it is :
1. Saved the body of mail into a file
2. Running the bellow python script to replace the characters and overwrite the original file.

# Import the `sys` and `os` modules.
import sys
import os
# Define the `remove_diacritics()` function.
def remove_diacritics(text):
"""
This function removes diacritics from text and replaces them with their Latin equivalent.
Arguments:
text: The text from which the diacritics will be removed.
Returns:
The text without diacritics.
"""
# Create a list of all Romanian diacritics, both lowercase and uppercase.
diacritics = ["Å£","â", "ă", "î", "È™", "È›", "Ș", "Èš", "á", "é", "Ã", "ó", "Å‘", "ú", "ü", "ű"]
# Create a list of all the Latin equivalents of the diacritics.
no_diacritics = ["t","a", "a", "i", "s", "t", "S", "T", "a", "e", "i", "o", "o", "u", "u", "u"]
# Replace all diacritics with their Latin equivalents.
for i in range(len(text)):
if text[i] in diacritics:
text = text[:i] + no_diacritics[diacritics.index(text[i])] + text[i + 1:]
return text
# Define the `main()` function.
def main(filename):
# Read the input file.
with open(os.path.join("New", filename), "r", encoding="utf-8") as f:
text = f.read()
# Remove the diacritics from the text.
text_without_diacritics = remove_diacritics(text)
# Write the text without diacritics back to the original file.
with open(os.path.join("New", filename), "w", encoding="utf-8") as f:
f.write(text_without_diacritics)
# Check if the input file exists.
if not os.path.exists(os.path.join("New", filename)):
raise FileNotFoundError(f"The input file {filename} does not exist.")
# Call the main function with the input file name as an argument.
main(filename)
