Inserting string with special character in database

Rails
1

Hi all.
I am having trouble in reading string containing special characters from
file and storing them in database. For example, for string like
‘\x89\xA5\xCFI w…’
it throws error “Incorrect string value”. The string should be wrappped
in duoble quotes, but i didn’t find any method to do so. If any one has
solution please help. I need it very badly.
Thanks.

Which database and what character set, e.g. UTF-8, Latin1, ASCII? Rails
now
defaults to UTF-8, but most databases default to Latin1.

you can give .to_s to convert into string.

a= 123
eg: a.to_s

The first character is a control code in UTF-8, HTJ. I’ve tried
assigning and
saving the above character strings in the Rails console. The saved and
retrieved string is empty, but I’m not seeing the error “Incorrect
string
value”. What is throwing this error? I also don’t understand the part
about
wrapping in double quotes. Why can’t you modify your program to change
single
to double quotes?

Hi Jeffrey,
Your question solved my trouble. I set the database character set to
Latin1 and it worked. It took the string with special character in DB.

Thanks.
