Nisam ni ja probao, ali me zaintrigiralo kakva je specifikacija formata, i ukratko tekst mora da bude po Unicode encodingu, a pretpostavljam da i font mora da bude ‘embedovan’. Uostalom, evo šta kažu na http://en.wikipedia.org/wiki/EPUB (boldovao sam bitne delove):
Open Publication Structure 2.0
An EPUB file uses XHTML 1.1 (or DTBook) to construct the content of a book as of version 2.0. This is different from previous versions (OEBPS 1.2 and earlier) which used a subset drawn from XHTML. There are, however, a few restrictions on certain elements. The mimetype for XHTML documents in EPUB is application/xhtml+xml.[8] For a table of the required XHTML modules and a description of the restrictions, please see Section 2.2 of the specification.
Styling and layout is performed using a subset of CSS 2.0, referred to as OPS Style Sheets. This specialized syntax requires only a portion of CSS properties to be supported by reading systems and adds a few custom ones. Some custom ones are oeb-page-head, oeb-page-foot, and oeb-column-number. Font-embedding can be accomplished using the @font-face property, as well as including the font file in the OPF’s manifest (see below). The mimetype for CSS documents in EPUB is text/css.[8] For a table of supported properties and detailed information, please see Section 3.0 of the specification.
EPUB also requires that PNG, JPEG, GIF, and SVG are supported for image types. These use the mimetypes image/png, image/jpeg, image/gif, image/svg+xml respectively. Other media types are allowed, but creators must include alternative renditions in supported types.[8] For a table of all required mimetypes, see Section 1.3.7 of the specification.
Unicode is required, and content producers must use either UTF-8 or UTF-16 encoding.[8] This is to support international and multilingual books. However, reading systems are not required to provide the fonts necessary to display every unicode character, though they are required to display at least a placeholder for characters that cannot be displayed fully.
Kako ja vidim, problem je u jednom od ova dva:
- ili originalni tekst nije Unicode
- ili reader na iPadu prikazuje placeholder umesto karaktera
Jesi li probao fajl da otvaraš na Macu sa nekim od ePub readera? Ako nisi, savetujem ti da prvo uspeš na Macu da dobiješ željeni rezultat, a tek onda na iPadu, pa ako ne dobiješ naša slova i na iPadu, pravac na http://www.apple.com/feedback da postaviš feature request.
Takođe, imaš li neku knjigu već u ePub formatu koja ima ‘naša’ slova i kako se ona prikazuje na iPadu?
Linkovao sam Wikipediju, jer je http://www.idpf.org/specs.htm koji je zvaničan pomalo rogobatan i strog (a specifikacije moraju da budu takve); ona mu dođe kao ‘tumačenje zakona’ u odnosu na sam zakon. B)
