Replacing Unicode Characters

Hi Experts,

I have a 100+ page book in MS Word that was written in a Cyrillic font over 10 years ago. The font is nothing fancy, it was just designed simply to use the standard US Keyboard to map and output Cyrillic characters. Nowadays, as we all know all OS have Cyrillic, and all World characters built in, and it is just a matter of enabling them.

My question is, how would I convert my book into the Unicodes for Cyrillic?

I used to code in VBA, but haven't done so in years. Now I code in PHP, and if I was to code it in PHP, I would do a 2-D array, with the first layer having 64 elements (the Macedonian alphabet has 32 letters) and it would look something like this:

[0]
    [letter] => A
    [Ascii] => 64
    [Uni] => 1040
[1]
    [letter] => B
    [Ascii] => 65
    [Uni] => 1041

Then, I would loop  through through array and use str_replace

Would this be possible in VBA, and  maybe even to run it through Access as for other files, other fonts has been used with slightly different mappings.

By the way, I am using the following Unicode Table
