I'm building a website using drupal. I would like to know how I can display the following characters. I have tried everything thing that came to my mind but it doesn't work. The Ckeditor  doesn't work. Below are the characters
Ị
ị
Ọ
ọ
Ụ
ụ
Ṅ
ṅ

The problem is that after inserting and clicking on "save", the whole characters will change to ?(question mark). I need some help please.

use numerical HTML encoding of the Unicode characters

find a table of the translation here http://www.utf8-chartable.de/unicode-utf8-table.pl?start=7808&number=1024&utf8=0x&unicodeinhtml=hex

example for : Ộ use

Ộ

Hmmm. . . . .

Thanks for your concern. I have tried that many times but it doesn't help. After using the HTML encoding, it works perfectly, but the moment I upgrade the site or make some certain changes, everything will go back to “?".

The only option that can make it work even after upgrading the site is by adding [b]"" [/b]sign e.g "ṅ" But the issue here is that those signs will appear on the front page which make it looks like this [b]"Ọ" [/b]in the frontpage. What else can I do please.
