[mkgmap-dev] multi-word street search

I don't know details about MDR format but what is bothering me is the 
dual format of labels used in creating index. Label can be in Garmin 
format, with special codes for shields and some separators, or with 
"clean" format, where special codes are removed or replaced by space.

What is unclear for me, is how to use offset inside labels, since offset 
to a word in Garmin format could be different than offset to the same 
word in clean format. This could be a bigger problem for Unicode or 
ASCII labels (if these are supported for index). That's why I'm using 
code-page=1252 at a moment.

I have moved changes from mixed-index to trunk and compiled a map of 
Europe (I like option drive-on=detect). I'm using my own style, where 
street names aren't prefixed with street number in a shield - this 
doesn't look good in nuvi. I have tried searches proposed by Carlos in 

Avenida - gives too much results to find proper street,
Avenida de ab - easy to find and  correct search,
Za-P-2661 - correct search,
nunez - too many results to find Abelardo Nuñez

I think for code-page=1252 index works correctly. There could be 
problems, but current results are encouraging.
