I have a problem storing language specific chars in MySQL even with utf8_unicode_ci on db/tables/fields.
Here's an example. I have entered 'дфрывафрв' value in 'headline' field via HTML form. When I retrieve the field's value using PHP and display it on some HTML page, it displays correctly. But when I checked the same field value in phpMyAdmin, it looked terrible, like this:
I have tried running the following query:
Code: Select all
SELECT * FROM news WHERE headline='дфрывафрв'
And of course it did not work (no records found). So, that means I am unable to do searches on db when storing records with language specific chars.
Anyone could explain me how to solve the problem? I thought utf8_unicode_ci would make it all fine.

Well, this seems to work but that doesn't solve another problem: I cannot use my string truncating function. It takes string and character count as arguments and returns truncated string with length <= character count without chopping parts of words (I use it with news items - it allows me to display a part of news item).
Maybe converting each char to html equivalent before storing in db (you know those &#int;)? But that's awkward...
There must be a way to store chars normally...

If you store the data in UTF-8, then the multibyte string systems in PHP can handle it..

As I mentioned before, everything is stored in UTF-8, but that does not allow me to truncate strings.
Code: Select all
function truncate($str, $chars)
{
$str = substr($str, 0, $chars + 1);
$length = strlen($str);
for ($i = $length - 1; $i > 0; $i--)
{
if (substr($str, $i, 1) == ' ')
{
$check = $i;
break;
}
}
if (isset($check))
{
$str = substr($str, 0, $check + 1) . '...';
} else
{
$str = '';
}
return $str;
}
$str = 'ąeęąčėę ūųūĮŠĮŠĖ įšęįąę ąčęę ąčę ąą ąąą šėš';
echo truncate($str, 40);
You should get this:
Code: Select all
ąeęąčėę ūųūĮŠĮŠĖ įšęįąę ąčęę ąčę ąą ąąą ...
But you'll get this:
Code: Select all
ąeęąčėę ūųūĮŠĮŠĖ ...
Still can't find a solution...

your "truncate" is functioning off of bytes, not characters.
