Sobre los archivos TXTComparativa de ventajas
FB2 Ventajas
- Pure XML — trivial to parse, search, and transform.
- Single-file ebooks with inline images.
- Excellent on low-powered e-readers.
- De-facto standard in Russian-language ebook ecosystem.
- Simple structure makes conversion to any other format straightforward.
TXT Ventajas
- Universally readable — every operating system, every editor, every programming language.
- Zero metadata overhead: the file size equals the character count (for ASCII).
- Safe to diff, grep, version-control, and pipe through command-line tools.
- Immune to format obsolescence: a text file from 1970 still opens today.
- Tiny footprint for structured data like logs or configuration.
Limitaciones
FB2 Limitaciones
- No styling, no custom fonts, no fixed layouts.
- Minimal Western-language tooling.
- Kindle and Apple Books do not support FB2 natively.
- Non-fiction with complex typography (textbooks, cookbooks) is a poor fit.
TXT Limitaciones
- No styling, images, or embedded structure — just characters.
- Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
- Line-ending differences between OSes still cause subtle bugs today.
- No way to carry hyperlinks, tables, or formatting without a convention on top (like Markdown).

EPUB is the open ebook standard — it plays on every e-reader except older Kindles and in every major ebook app. PDF is better for fixed-layout content (textbooks, coffee-table books) and printing. Pick EPUB when the ebook is reflowable text, PDF when the layout matters more than the reading experience.
