    addTTFfont()

    Convert and add the selected TrueType or Type1 font to the fonts folder (that must be writeable).

    public static addTTFfont(string $fontfile[, string $fonttype = '' ][, string $enc = '' ][, int $flags = 32 ][, string $outpath = '' ][, int $platid = 3 ][, int $encid = 1 ][, bool $addcbbox = false ][, bool $link = false ]) : string|false
    Parameters
    $fontfile : string

    Font file (full path).

    $fonttype : string = ''

    Font type. Leave empty for autodetect mode. Valid values are: TrueTypeUnicode, TrueType, Type1, CID0JP = CID-0 Japanese, CID0KR = CID-0 Korean, CID0CS = CID-0 Chinese Simplified, CID0CT = CID-0 Chinese Traditional.

    $enc : string = ''

    Name of the encoding table to use. Leave empty for default mode. Omit this parameter for TrueType Unicode and symbolic fonts like Symbol or ZapfDingBats.

    $flags : int = 32

    Unsigned 32-bit integer containing flags specifying various characteristics of the font (PDF32000:2008 - 9.8.2 Font Descriptor Flags): +1 for fixed font; +4 for symbol or +32 for non-symbol; +64 for italic. Fixed and Italic mode are generally autodetected so you have to set it to 32 = non-symbolic font (default) or 4 = symbolic font.

    $outpath : string = ''

    Output path for generated font files (must be writeable by the web server). Leave empty for default font folder.

    $platid : int = 3

    Platform ID for CMAP table to extract (when building a Unicode font for Windows this value should be 3, for Macintosh should be 1).

    $encid : int = 1

    Encoding ID for CMAP table to extract (when building a Unicode font for Windows this value should be 1, for Macintosh should be 0). When Platform ID is 3, legal values for Encoding ID are: 0=Symbol, 1=Unicode, 2=ShiftJIS, 3=PRC, 4=Big5, 5=Wansung, 6=Johab, 7=Reserved, 8=Reserved, 9=Reserved, 10=UCS-4.

    $addcbbox : bool = false

    If true includes the character bounding box information on the php font file.

    $link : bool = false

    If true link to system font instead of copying the font data (not transportable) - Note: do not work with Type1 fonts.

    arrUTF8ToUTF16BE()

    Converts array of UTF-8 characters to UTF16-BE string.<br> Based on: http://www.faqs.org/rfcs/rfc2781.html <pre> Encoding UTF-16:

    public static arrUTF8ToUTF16BE(array<string|int, mixed> $unicode[, bool $setbom = false ]) : string

    Encoding of a single character from an ISO 10646 character value to UTF-16 proceeds as follows. Let U be the character number, no greater than 0x10FFFF.

    1. If U < 0x10000, encode U as a 16-bit unsigned integer and terminate.

    2. Let U' = U - 0x10000. Because U is less than or equal to 0x10FFFF, U' must be less than or equal to 0xFFFFF. That is, U' can be represented in 20 bits.

    3. Initialize two 16-bit unsigned integers, W1 and W2, to 0xD800 and 0xDC00, respectively. These integers each have 10 bits free to encode the character value, for a total of 20 bits.

    4. Assign the 10 high-order bits of the 20-bit U' to the 10 low-order bits of W1 and the 10 low-order bits of U' to the 10 low-order bits of W2. Terminate.

    Graphically, steps 2 through 4 look like: U' = yyyyyyyyyyxxxxxxxxxx W1 = 110110yyyyyyyyyy W2 = 110111xxxxxxxxxx

    Parameters
    $unicode : array<string|int, mixed>

    array containing UTF-8 unicode values

    $setbom : bool = false

    if true set the Byte Order Mark (BOM = 0xFEFF)
