<!-- doc/src/sgml/README.non-ASCII --> Representation of non-ASCII characters -------------------------------------- Find non-ASCII characters using: grep --recursive --color='auto' -P '[\x80-\xFF]' . Convert to HTML4 named entity (&) escapes ----------------------------------------- We support several output formats: * html (supports all Unicode characters) * man (supports all Unicode characters) * pdf (supports only Latin-1 characters) * info While some output formatting tools support all Unicode characters, others only support Latin-1 characters. Specifically, the PDF rendering engine can only display Latin-1 characters; non-Latin-1 Unicode characters are displayed as "###". Therefore, in the SGML files, we can only use Latin-1 characters. We can use UTF8 representations of Latin-1 characters, or HTML entities of Latin-1 characters, e.g., Álvaro. Do not use UTF numeric character escapes (&#nnn;). When building the PDF docs, problem characters will appear as warnings.
