Sort order for Simplified Chinese (pinyin)

Question

FrameMaker 10 (Windows)
It seems that if I specify the sort order for Simplified Chinese (pinyin) on the reference page,
index entries that start with "i" and "v" are not shown under their corresponding group titles.
(I assume that this may be due to the fact that pinyin words never start with these letters.)
If I have an entry that starts with an English word like "IP," it appears under the "J" group.
I want the entry to appear under the "I" group. How can I do this?
I have the IX reference page set up as follows:
GroupTitlesIX paragraph
Symbols[\];Numerics[0];A;B;C;D;E;F;G;H;I;J;K;L;M;N;O;P;Q;R;S;T;U;V;W;X;Y;Z;
SortOrderIX paragraph
<$symbols><$numerics><$alphabetics><$pinyin>
I've also tried:
SortOrderIX paragraph
<$symbols><$numerics><$pinyin>
Thanks in advance.

I sort of found a workaround, but it may lead to other problems, so use it at your own risk.
It also requires a bit of work.
The idea is to use the sort order for Japanese by specifying the following in the IX reference page.
Symbols[\ ];数字[0];A;B;C;D;E;F;G;H;I;J;K;L;M;N;O;P;Q;R;S;T;U;V;W;X;Y;Z;あ;い;う;え;お;か;き;く;け;こ;さ;し;す;せ;そ ;た;ち;つ;て;と;な;に;ぬ;ね;の;は;ひ;ふ;へ;ほ;ま;み;む;め;も;や;ゆ;よ;ら;り;る;れ;ろ;わ;ん;[　]
<$symbols><$numerics><$alphabetics><$kana>
Then, you need to capitalize the first letter in the bracket used for sorting for every index entry.
Example:
Instead of
画面[hua4mian4]
specify
画面[Hua4mian4]
Now, I'm wondering if there is a way to do a search and replace on all index entries to capitalize the first letter...
