It is often frustrating for learners of French language when it is not possible to type a specific character. Some people cut-and-paste them from MS Word, which has an automatic spellchecker-corrector, some use Alt+nnnn combinations... But this is cumbersome.
The easiest way for a person using MS Windows and owning a Standard-US physical keyboard is to install French (Canada) layout. French(Canada) layout is more convenient to use for previous Standard-US keyboard user comparing to French(France) layout because the vast majority of letters are in the same places as in the Standard-US keyboard (QWERTY - not AZERTY).
The problem is that even in French(Canada) layout some letters are not obvious how to type. Especially so are the letters: æ, œ, ï, ÿ, ë, ù.
But let's formulate the question in a generic form:
How to type the following letters on the French(Canada) keyboard:
à â æ (à, câlin, æsthésie) [accent aigu, accent circonflexe, e dans l'a] ç (ça) [cédille] è é ê ë (mère, parlé, être, Noël) [accent grave, ...] î ï (naître, naïve) [tréma] ô œ (côte, œuf) [e dans l'o] ù û ü (où, coûter, capharnaüm) ÿ (Croÿ)
I searched on internet but could not find a satisfactory answer.
