Description:
If I try to preview/save a page containing math markup such as "<math>\alpha^2+\beta^2=1</math>", then I get the following error:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
SELECT math_outputhash,math_html_conservativeness,math_html,math_mathml FROM math WHERE math_inputhash = '�S\x1c�@��uo�&\x10Z�f�' LIMIT 1
from within function "MathRenderer::_recall". MySQL returned error "1267: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_unicode_ci,COERCIBLE) for operation '=' (sql)".

Some people suggested setting $wgDBmysql5 to false which did not work. MySQL lists the math table as having a latin1_swedish_ci collation; all text/varchar columns on that table also have a latin1_swedish_ci collation.

FYI, my MySQL version is 5.0.26

Any help would be appreciated.

Thanks,
Ross
