I looked quickly into it, but it will require somebody who has experience in dealing with international characters.

1) I've changed the function as posted here, so at least I got the letters now visible

2) However, Lexikon still didn't show properly the words starting with a particular Vietnamese letter. I checked and it seems like Lexikon doesn't extract properly the initials of each word and writes them into the database (line 114 in submit.php):

Quote:

$init = substr($term, 0, 1);

In my case Lexikon was writing into the database "#" as initial for each words starting with Vietnamese character, so when Lexikon was reading the words back from the database, it grouped them automatically under "Other"

3) I then manually changed the initials in the database, so now Lexikon was reading them, but it was putting them in multiple categories. For example, the word Âcuon was counted under "A" and under "Â"

Unfortunately, I don't have the time and skills to solve it. But it seems to me that the problems are:

1) To properly write the initial of the word starting with Vietnamese characters into the database

2) When reading the words from the database, Lexikon has to place them into the right character group, without any duplications.

Sorry, I couldn't be of more help, but hopefully some experts in internationalization will jump in...
