# Spanish PDF to EPUB: accents, «» and ¿?

Source: https://epubcc.com/cases/spanish-pdf/ (updated 2026-11-04)

Spanish text converts cleanly when the PDF has real Unicode text: accents, ñ, «» quotes and inverted ¿? marks come through unchanged and the EPUB is tagged as Spanish. On a 50-page Spanish Wikipedia article our 8-gram recall is 0.941, below pdf_oxide's 0.963.

Problem: Accented letters, ñ, «» and “” quotes, inverted question and exclamation marks, dialogue dashes and superscript reference calls, set in justified text.

- Limitation: pdf_oxide extract_text (0.963) and OpenDataLoader (0.954) have a higher 8-gram recall than our engine (0.941) on this document.
- Limitation: In the sample, a line with a superscript «[cita requerida]» was split in three: «VI duque», then «y», then «de Béjar grande de España». The words are all there but out of order.
- Limitation: Images that float beside the text break the paragraph they interrupt (see the text-wrapped-around-images case); the pages shown here have none.
- Limitation: Wikipedia references leave out tables and infoboxes, so precision is low for every engine.
