TXT vs XHTML
Um comparativo detalhado de Plain Text e XHTML Document — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.

Sobre os arquivos XHTMLComparativo de vantagens
TXT Vantagens
- 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.
XHTML Vantagens
- Rigorous XML syntax — can be parsed with any XML tool.
- Native EPUB and DocBook support.
- Enforces clean markup — no sloppy error recovery.
- Namespaces allow mixing SVG, MathML, and XHTML in one document.
Limitações
TXT Limitações
- 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).
XHTML Limitações
- Browsers reject XHTML with strict MIME on any markup error — harsh failure mode.
- Authoring is more tedious than HTML5.
- Not served by ~99% of the web.
- Largely superseded by HTML5.

Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to TXT (frames, legacy macros) may flatten to static content in the target format.
