Orange Paranoid: I think the problem is that you didn't give enough context of your question. Now I understand that your problem is to use a letter to teach children to read. I don't know what materials you use for this, but care must be taken with all printed material is to use alphabets that do not generate ambiguities, if you read my previous reply you will notice that it had already referred the case that in some designs a uppercase "i" is confused with a lowercase "l". You have mentioned the case of lowercase "t" that can be confused with lowercase "f", similarly "m" sometimes be confused with "r" and "n" together. Create or edit fonts is not a trivial matter, it often requires a rare combination of skills coupled with years of study and practice in addition to many more years of practice and inspiration before achieving a decent result. We don't need to reinvent the wheel. When one of your children confuse one letter with another you should not argue with him/her saying that is confusing or in error. Suffice it to you to explain that just as there are different colors and styles for the same garment, for example trousers or a shirt, so there are subtle differences in writing, ranging from personal taste in calligraphy, to fashion reflected in typography . However, at the end all the letters retain their essence. You may find it difficult to visualize when just beginning to read and write, but eventually your eye will become familiar and be able to notice them without problem. Adrian Frutiger is a Swiss typographer who has some wonderful books on this topic that you could serve to clarify the picture and knew how best to address this issue with your children. In your case as a teacher you must ensure that your handwriting is clear and not confuse your children, for the typographic part, you should seek some font that is easy to read and provide for these children to have confidence in reading and writing. On the other hand, children who have been confused by the letters, would not be prone to dyslexia? I don't know if this could be useful, but take a look: http://opendyslexic.org/ Here is another interesting project also: http://www.sassoonfont.co.uk/ Maybe you don't need typefaces for dyslexic children, but those letters are designed carefully for avoid confusion and could be useful for you also: http://bdatech.org/what-technology/typefaces-for-dyslexia/#sassoon I find very interesting this particular topic, perhaps the list of Fedora is not the best place to ask, but if this has helped you and you have more questions, glad I can help you, suggest other options or contact with some typographers that can help with the technical part.
