Php remove all non utf 8 characters
If you apply Show I made a function that addresses all this issues. It´s called You dont need to know
what the encoding of your strings is. It can be Latin1 (ISO8859-1), Windows-1252 or UTF8, or the string can have a mix of them. I did it because a service was giving me a feed of data all messed up, mixing those encodings in the same string. Usage:
I've included another function, Encoding::fixUTF8(), which will fix every UTF8 string that looks garbled product of having been encoded into UTF8 multiple times. Usage:
Examples:
will output:

8 Using a regex approach:
It searches for UTF-8 sequences, and captures those into group 1. It also matches single bytes that could not be identified as part of a UTF-8 sequence, but does not capture those. Replacement is whatever was captured into group 1. This effectively removes all invalid bytes. It is possible to repair the string, by encoding the invalid bytes as UTF-8 characters. But if the errors are random, this could leave some strange symbols.
EDIT:
I have also sped up the match a little. Instead of matching each character separately, it matches sequences of valid UTF-8 characters. answered Sep 9, 2009 at 19:49

technoaryatechnoarya 2133 silver badges5 bronze badges 4 UConverter can be used since PHP 5.5. UConverter is better the choice if you use intl extension and don't use mbstring.
htmlspecialchars can be used to remove invalid byte sequence since PHP 5.4. Htmlspecialchars is better than preg_match for handling large size of byte and the accuracy. A lot of the wrong implementation by using regular expression can be seen.

Alix AxelAlix Axel 148k91 gold badges388 silver badges493 bronze badges So the rules are that the first UTF-8 octlet has the high bit set as a marker, and then 1 to 4 bits to indicate how many additional octlets; then each of the additional octlets must have the high two bits set to 10. The pseudo-python would be:
This same logic should be translatable to php. However, its not clear what kind of stripping is to be done once you get a malformed character. answered Sep 9, 2009 at 18:49

If you're concerned yes it retains spaces as valid characters. Did what I needed. It removes widespread nowadays emoji-characters that don't fit into MySQL's 'utf8' character set and that gave me errors like "SQLSTATE[HY000]: General error: 1366 Incorrect string value".
