# Check 8bit escape character with charset conversion:
# For "a LIKE b ESCAPE c" expressions,
# escape character is converted into the operation character set,
# which is result of aggregation of character sets of "a" and "b".
# "c" itself doesn't take part in aggregation, because its collation
# doesn't matter, escape character is always compared binary.
# In the example below, escape character is converted from koi8r into cp1251:

select _cp1251'andre%' like convert('andre<72>%' using cp1251) escape '<27>';
