How do I search for all rows containing a given unicode character in Postgres

I am after all cells containing the 'LINE SEPARATOR' (U+2028) unicode point. Normally this is encoded as \u+2028 or something similar. However googling how this translates to SQL has given various options none of which seem to work ((N'2028'), set @hexstring = '2028';, vchar(2028))

SELECT * FROM myTable WHERE desc LIKE '% [SOME WAY TO ESCAPE U+2028 ] %'
Solution

  • ANSI SQL answer, use a Unicode character string literal:

    SELECT * FROM myTable WHERE desc LIKE U&'%\2028%'
