> Simple RTF editors are surprisingly few RTF isn’t standardized and, reading https://en.wikipedia.org/wiki/Rich_Text_Format https://en.wikipedia.org/wiki/Rich_Text_Format I get the impression there are fairly wide differences between versions. From the same page, it also isn’t simple: - files can use at least 18 different text encodings. - you can include Unicode code points, but if you do, they “must be followed by the nearest representation of this character in the specified code page” - if you want to create a table in a RTF file, it seems you have to include an OLE object - for compatibility with existing files, it seems an editor will have to support Windows meta file format. So, I would guess any simple RTF editor would be incompatible with a significant fraction of existing RTF files.
