Hi! It has been some time since my last post but I haven't forgotten about you guys :)

Bit of an oddball query, this one... but I bet someone knows one or two ways to do it.

I'm creating search indexes with Perl for my Chinese dictionary mobile app and am hitting a problem where the (Perl) sorted keys - Chinese characters - are not in exactly the same order as the binary search on-device is expecting them to be.

In real terms, there are 165910 index records and 188 of them are unreachable on-device because the sort order is slightly different between Perl's standard string sort and C#'s String.Compare function (with "en-US" culture).

I've played around for weeks with the culture settings and this 188 unreachable number is the optimal result I have achieved. So 2 questions:

1. (long shot) has anyone seen this issue before so knows the magic incantation to get Perl and C# to agree 100% on sort order for UTF-8?

2. (failing that) how do I get Perl to sort by Unicode code point (i.e. the raw underlying \u{xxxx} value, because I can probably force C# to do it that way as an exception for this index?

Any help much appreciated.

perl -le "s,,reverse killer,e,y,rifle,lycra,,print"

    [Eily]: muthusathish ok, the fact that you can't tell what perl has to do with it proves it: this is not perl
