Hi,
I'm a testing a new rendering option for the <math /> element and had
problems to store MathML elements in the database field
math_mathml which is of type text.
The MathML elements contain a wide range of Unicode characters like the
INVISIBLE TIMES that is encoded as 0xE2 0x81 0xA2 in UTF-8 or even 4 byte
chars like MATHEMATICAL BOLD CAPITAL A 0xF0 0x9D 0x90 0x80 .
In some rar cases I had problem to retrieve the stored value correctly from
MySQL.
To fix that problem I'm now using the PHP functions utf8_encode /decode to
which is not a very intuitive solution.
Do you know a better method to solve this issue without to change the
database layout.
