Diacritic marks (extra marks to help non-native speakers with pronunciation) mainly appear in loanwords such as "naïve" and "façade". As such words become a normal part of English vocabulary, there is a tendency to remove the diacritics, as has happened with old borrowings such as "hôtel", from French. Informal English writing tends to get rid of diacritics because of their absence from the keyboard, while professional copywriters and typesetters tend to include them, such as Microsoft Word. Words that are still thought to be foreign tend to keep them; for example, the only spelling of "soupçon" found in English dictionaries (the OED and others) uses the diacritic. Diacritics are also more likely to be kept where there would otherwise be confusion with another word (for example, "résumé" (or "resumé") rather than "resume"), and, rarely, even added (as in "maté", from Spanish "yerba mate", but following the pattern of "café", from French).
