NOTES

Precise pixel layouts for mosaic graphics:

Based on a 6x10 grid of pixels:

............  000000111111  ..0000..1111  
......##....  000000111111  ..0000..1111
....##..##..  000000111111  ............

............  444444555555  ..4444..5555
............  444444555555  ............

Mosaic characters are not smoothed, and smoothing also doesn't apply
between mosaic characters and adjacent alphanumeric characters.

The SAA5050 series is generally compatible with the G0 primary
character sets defined by ETSI EN 300 706 V1.2.1:

SAA5050: Latin with English option
SAA5051: Latin with German option
SAA5052: Latin with Swedish option
SAA5053: Latin with Italian option
SAA5054: Latin with French option

SAA5057: Cyrillic (Russian)

There's no ETSI EN 300 706 character set that corresponds to the
SAA5055.  The ETSI EN 300 706 Hebrew set is almost identical to the
SAA5056 set, except that the old Sheqel sign on the SAA5056 is
replaced by the new Sheqel sign in ETSI EN 300 706.

ETSI EN 300 706 to Unicode mapping:

ZVBI, the Zapping teletext decoder has opinions on this:

 * Exceptions:
 * ETS 300 706 Table 36 Latin National Subset Turkish character
 * 0x23 Turkish currency symbol is not representable in Unicode,
 * translated to private code U+E800. Was unable to identify all
 * Arabic glyphs in Table 44 and 45 Arabic G0 and G2, these are
 * mapped to private code U+E620 ... U+E67F and U+E720 ... U+E77F
 * respectively. Table 47 G1 Block Mosaic is not representable
 * in Unicode, translated to private code U+EE00 ... U+EE7F.
 * (contiguous form has bit 5 set, separate form cleared).
 * Table 48 G3 Smooth Mosaics and Line Drawing Set is not
 * representable in Unicode, translated to private code U+EF20
 * ... U+EF7F.
 *
 * Note that some Teletext character sets contain complementary
 * Latin characters. For example the Greek capital letters Alpha
 * and Beta are reused as Latin capital letter A and B, while a
 * separate code exists for Latin capital letter C. This function
 * is unable to distinguish between uses, so it will always translate
 * Greek A and B to Alpha and Beta, C to Latin C.
 *
 * Private codes U+F000 ... U+F7FF are reserved for DRCS.

Latin G0 primary set is mostly ASCII, with the exception of:

Teletext mosaic graphics are largely not represented in Unicode, but
there are a few characters that are already there for 4-cell mosaics:

U+0020 SPACE
U+2588 FULL BLOCK
U+258C LEFT HALF BLOCK
U+2590 RIGHT HALF BLOCK

ITU-T Recommendation T.100 is another standard that encodes 6-cell
mosaic graphics.
