We have problem with current wiki encoding UTF-8 while saving pages containing SQL queries that are documented at our wiki.

Original query before it’s documented on wiki page:

AND (T2."U_NAME" = N'[%23]' OR '[%23]' = '')
AND (T1."CreateDate" >= '[%24]' OR '[%24]' = '')
AND (T1."CreateDate" <= '[%25]' OR '[%25]' = '')
AND ((T0."ShortName" = '[%26]') OR ('[%26]' = ''))

After a page with query is saved:

AND (T2."U_NAME" = N'[#]' OR '[#]' = '')
AND (T1."CreateDate" >= '[$]' OR '[$]' = '')
AND (T1."CreateDate" <= '[%]' OR '[%]' = '')
AND ((T0."ShortName" = '[&]') OR ('[&]' = ''))
