## Description

A GMimeFilter which is meant to determine the best charset and/or transfer encoding suitable for the stream which is filtered through it.

## Details

### GMimeFilterBest

    typedef struct _GMimeFilterBest GMimeFilterBest;

A filter for calculating the best encoding and/or charset to encode the data passed through it.

### enum GMimeFilterBestFlags

    typedef enum {
    	GMIME_FILTER_BEST_CHARSET  = (1 << 0),
    	GMIME_FILTER_BEST_ENCODING = (1 << 1)
    } GMimeFilterBestFlags;

Bit flags to enable charset and/or encoding scanning to make educated guesses as to what the best charset and/or encodings to use for the content passed through the filter.

`GMIME_FILTER_BEST_CHARSET` | Enable best-charset detection.
`GMIME_FILTER_BEST_ENCODING` | Enable best-encoding detection.

### g_mime_filter_best_new ()

    GMimeFilter *       g_mime_filter_best_new              (GMimeFilterBestFlags flags);

Creates a new GMimeFilterBest filter. `flags` are used to determine which information to keep statistics of. If the GMIME_FILTER_BEST_CHARSET bit is set, the filter will be able to compute the best charset for encoding the stream of data filtered. If the GMIME_FILTER_BEST_ENCODING bit is set, the filter will be able to compute the best Content-Transfer-Encoding for use with the stream being filtered.

Note: In order for the `g_mime_filter_best_charset()` function to work, the stream being filtered MUST already be encoded in UTF-8.

`flags` : | filter flags
Returns : | a new best filter with flags `flags`.

### g_mime_filter_best_charset ()

    const char *        g_mime_filter_best_charset          (GMimeFilterBest *best);

Calculates the best charset for encoding the stream filtered through the `best` filter.

`best` : | best filter
Returns : | a pointer to a string containing the name of the charset best suited for the text filtered through `best`.

### g_mime_filter_best_encoding ()

    GMimeContentEncoding  g_mime_filter_best_encoding       (GMimeFilterBest *best,
                                                             GMimeEncodingConstraint constraint);

Calculates the most efficient Content-Transfer-Encoding for the stream filtered through `best` that fits within the encoding `constraint`.

`best` : | a GMimeFilterBest
`constraint` : | a GMimeEncodingConstraint
Returns : | the best encoding for the stream filtered by `best`.
