Detailed Description
Provides encoding detection capabilities.
Searches for encoding declaration inside raw data – meta and xml tags. In the case it can't find it, uses heuristics for specified language.
If it finds unicode BOM marks, it changes encoding regardless of what the user has told
Intended lifetime of the object: one instance per document.
Typical use:
Do not mix decode() with decodeWithBuffering()
Guess encoding of char array

Constructor & Destructor Documentation
KEncodingDetector::KEncodingDetector | ( | ) |
Default codec is latin1 (as html spec says), EncodingChoiceSource is default, AutoDetectScript=Semiautomatic.
Definition at line 646 of file kencodingdetector.cpp.
KEncodingDetector::KEncodingDetector | ( | QTextCodec * | codec, |
EncodingChoiceSource | source, | ||
AutoDetectScript | script = None |
||
) |
Allows to set Default codec, EncodingChoiceSource, AutoDetectScript.

Member Function Documentation

Analyze text data.
- Returns
- true if there was enough data for accurate detection
Definition at line 859 of file kencodingdetector.cpp.
QString KEncodingDetector::decode | ( | const char * | data, |
int | len | ||
) |
The main class method.
Calls protected analyze() only the first time of the whole object life
Replaces all null chars with spaces.
Definition at line 767 of file kencodingdetector.cpp.
bool KEncodingDetector::decodedInvalidCharacters | ( | ) | const |
This method checks whether invalid characters were found during a decoding operation.
Note that this bit is never reset once invalid characters have been found. To force a reset, either change the encoding using setEncoding() or call resetDecoder()
- Returns
- a boolean reflecting said state.
- Since
- 4.3
- See also
- resetDecoder() setEncoding()
Definition at line 839 of file kencodingdetector.cpp.
|
protected |
- Returns
- QTextDecoder for detected encoding
Definition at line 690 of file kencodingdetector.cpp.
QString KEncodingDetector::decodeWithBuffering | ( | const char * | data, |
int | len | ||
) |
Convenience method that uses buffering.
It waits for full html head to be buffered (i.e. calls analyze every time until it returns true).
Replaces all null chars with spaces.
- Returns
- Decoded data, or empty string, if there was not enough data for accurate detection
- See also
- flush()
Definition at line 789 of file kencodingdetector.cpp.
const char * KEncodingDetector::encoding | ( | ) | const |
Convenience method.
- Returns
- mime name of detected encoding
Definition at line 674 of file kencodingdetector.cpp.
|

Check if we are really utf8.
Taken from kate
- Returns
- true if current encoding is utf8 and the text cannot be in this encoding
Please somebody read https://en.wikipedia.org/wiki/UTF-8 and check this code...
Definition at line 586 of file kencodingdetector.cpp.
QString KEncodingDetector::flush | ( | ) |
Convenience method to be used with decodeForHtml.
Flushes buffer.
- See also
- decodeForHtml()
Definition at line 844 of file kencodingdetector.cpp.
|
protected |
This nice method will kill all 0 bytes (or double bytes) and remember if this was a binary or not ;)
Definition at line 563 of file kencodingdetector.cpp.
void KEncodingDetector::resetDecoder | ( | ) |
Resets the decoder.
Any stateful decoding information (such as resulting from previous calls to decodeWithBuffering()) will be lost. Will Reset the state of decodedInvalidCharacters() as a side effect.
- Since
- 4.3

Takes lang name after it were i18n()'ed.
Definition at line 1119 of file kencodingdetector.cpp.
bool KEncodingDetector::setEncoding | ( | const char * | encoding, |
EncodingChoiceSource | type | ||
) |
- Returns
- true if specified encoding was recognized
