This function repairs the given string.
The config parameter can be passed either as an array or as a string. If you pass it as a string, it means the name of the configuration file, otherwise it is interpreted as the options themselves. Check http://tidy.sourceforge.net/docs/quickref.html for an explanation about each option.
The encoding parameter sets the encoding for input/output documents. The possible values for encoding are: ascii, latin0, latin1, raw, utf8, iso2022, mac, win1252, ibm858, utf16, utf16le, utf16be, big5 and shiftjis.
Note: The optional parameters config and encoding were added in Tidy 2.0.
