Starting from version 3.0 SiteSupra is using capabilities of full text indexing and searching.
The field search of the content table has full text index.
Since MySQL does not support full text searching for UTF, SiteSupra uses its internal encoding for storing search data.
The internal SiteSupra encoding allows converting a text from UTF and back to UTF for the following charsets:
Charset
Description
1250
Central European
1251
Cyrillic
1252
Western European
1253
Greek
1254
Turkish
1257
Baltic
However, you can define your own way of storing search data.
