Zeichensatz (Code Page)

Ein Computer basiert auf dem Binärsystem, das heißt alle Informationen werden durch „0“ und „1“ dargestellt. Acht dieser Werte entsprechen einem Byte. Acht Stellen mit je zwei Möglichkeiten sind demnach 28 Varianten. Ein Byte kann also 256 unterschiedliche Werte haben. Einer dieser Werte wird auch Codepunkt genannt.
Bei einem Zeichensatz wird nun vereinbart, welche Bedeutung ein solcher Codepunkt hat. Meist finden sich diese Zuordnungen in Form einer Tabelle. Hier ein Beispiel:

 

Häufig verwendete Zeichensätze:

ASCII

7-bit-Zeichensatz (128 Zeichen), besonders geeignet für englische Texte
RTF (rich text format) baut darauf auf, HTML kann mit diesem Zeichensatz geschrieben werden

Windows- 1252/WinLatin1

Wird von Windows-Betriebssystemen verwendet

ISO-8859

Gruppe von Zeichensätzen (z.B. ISO-8859-1 oder 8859-5), die für die europäischen Sprachen normiert wurden. Jeder einzelne Zeichensatz verwendet den ASCII-Zeichensatz in den ersten 128 Stellen. Die übrigen Zeichen werden für Steuerzeichen und die sprachspezifischen Buchstaben verwendet, wie z.B. „ä“, „ü“ oder „ö“.

Unicode

Dieses Projekt wurde gestartet, um die Zeichen sämtlicher Sprachen in nur einem Zeichensatz zusammenzufassen. Dieser ist systemunabhängig, programmunabhängig, sprachunabhängig.
Alle aktuellen Betriebssysteme unterstützen mittlerweile Unicode.

Octopus Write & Draw Ink, waterproof ink for fountain pen, nib and brush, vegan

The Octopus Write & Draw inks are unique, smudge-proof and waterproof writing and drawing inks in a wide range of colours. They were developed for daily use in fountain pens and are also popular with graphic artists, illustrators, calligraphers and artists for writing, sketching, drawing and colouring with calligraphy pens, glass pens or brushes.

Each of the 38 brilliant shades inspires with its intense colour power thanks to its high, balanced pigmentation. In addition to a deep black and various shades of grey, the extensive colour palette also includes a particularly opaque white, which can be used on dark backgrounds.

During the development of the drawing ink, special attention was paid to its use in the fountain pen. The use of the finest colour pigments in a carefully balanced formula ensures high light fastness and a good, even ink flow without clogging the ink duct of the fountain pen. These pigmented writing inks also feature the excellent writing behaviour of the classic Octopus fountain pen inks. The Write & Draw drawing ink meets the requirements for document-proof ink according to DIN ISO 12757-2 and DIN ISO 14145-2 and is produced exclusively with vegan ingredients.
 
Writing enthusiasts love the razor-sharp typeface that can be achieved on fountain pen-suitable paper and the pleasant shading of the Write & Draw writing ink. Calligraphers can create the finest hairlines and impressive flourishing elements, while urban sketchers can draw precise outlines.

The ink dries waterproof in a very short time and can then be painted over with another shade of Octopus Write & Draw ink or watercolour. It is eraser-proof and most of the colours are also highlighter-proof.

Both pure and diluted with water, Octopus Write & Draw ink is excellent for colouring. Used undiluted, the waterproof ink convinces with its opacity. The many colours of Octopus drawing ink can be mixed with each other, but also with water. In this way, countless colour shades can be achieved for beautiful watercolour effects.

Unlike most other waterproof inks, Octopus Write & Draw can be used in a fountain pen without hesitation. However, care should be taken not to let the fountain pen dry out. We therefore recommend that you rinse and clean your writing instrument carefully after use to prevent the ink from drying up accidentally.

The Octopus special cleaner for pigmented inks is available for cleaning your writing Instruments.
