I cannot enter the characters you mentioned in the message above, but I checked all French letters, diatrics and ligatures such as "Àà, Ââ, Ææ" as listed in http://en.wikipedia.org/wiki/French_alphabet, all the characters there are accepted in FormsCentral. I logged a bug in our system on these phonetic characters. Thanks for your feedback!
I’m sorry, but I should have been more clear. We are working in phonetics for each language (as a way to help them learn the correct way to pronounce the sounds).
The symbols that are needed in transcribing the French language in the International Phonetics Alphabet (which is supported in Unicode fonts) are:
Each of the pure vowels are supported, it is the combining tilde that is not. If support for combining diacritical marks could be added to the provided font sets, all would be well.

Thanks for the details! There are some limitations in the product that FC doesn't support combining diacritical marks currently.
