Localization or an other solution

Hi,
As everybody knows, or at least guess, the Turkish-specific characters
is ordered incorrectly unless you don't have localization support. (For
example there is a letter like 's' but has a dot under it; this letter
must come after 's'; without localization support this and other
non-English ones come after 'z' )
According to the manual, localization causes the loose of performance.
Beside, I scare to use localization which is not familiar to me. Because
of these, I try to find an other solution. The one that I think on is- to use a seperate field for each of the fields
thatI want to order;- to put a correctly-sortable version of the data in the related field- and to use this extra
fieldsfor sorting purposes.
 
Example:
Original data: 'şimşek'
In extra field: 'szzimszzek'
Finally, my question is:
In a table which has 100.000 or more records, which one will be more
faster? Localization or this one.
Thanks in advance
