It depends on the language. In most languages, it's to indicate that the a should NOT be combined with the adjacent vowel, but pronounced in a separate syllable.
In German, however, it changes the sound of the vowel itself. (Specifically, on the letter a, it means it should be pronounced as "ay" instead of the usual "ah".)
A colon consists of two dots, one directly over the other, and it looks exactly like this :
The letters T and L are formed as asked.l and t from fiona1234
In linguistics, diaeresis, diæresis or dieresis, is the pronunciation of two adjacent vowels in two separate syllables rather than as a diphthong or vowel digraph, and also the name of the diacritic mark ( ¨ ) used to prompt the reader to pronounce adjacent vowels in this manner. For example the first two vowels in the word cooperate, which can be spelt co-operate or, using the diaeresis, coöperate.
I assume you mean no repetition to be ABC and not ABA OR AAB. That being said this is very straight forward. The first position can potentially have any of the 26 letters. the second position can only have 1 of 25 possible letters because one letter has already be selected for the first position. And the final position can only have 1 of 24 possible letters because two letters have already been selected for the first two positions. Just multiply the number of possibilities for each position together and you have your answer. 26 * 25 * 24 = 15600 possible combinations.
"Letters" are the 26 marks from 'A' through 'Z'. (A, B, C, D, E, . . . and so forth.) "Numbers" are the 10 marks from '0' through '9'. (0, 1, 2, 3, 4, . . . and so forth.) When you choose your password, you're supposed to put two of the first kind of marks, or two of the second kind of marks, in the password.
The two dots above a letter, you mean, would be called a diaeresis and/or an umlaut.
It is called a diersis or umlaut, depending on how it's being used.
It is an accent such as FARAAD
It means i typed two dots
It means that the "U" now says oo as in boo
There is two dots above the Mn, there your two S dots
I believe it is similar to madchen (with the a having two dots above it) in which case it would mean girl.
Do you mean, one dot above two dots? If that's what you intended, it means "therefore." I don't think ever seen two dots above one dot... wikipedia article on this: http://en.wikipedia.org/wiki/Therefore_sign

It depends on what langauge you are talking about. If you mean German: ä: pronounce it like the "a" in ham ö: pronounce it like the "ur" in murder ü: has no equivalent in English but can be described as pronouncing the sound ee with rounded lips. If you mean Russian: ё: pronounced like "yo" or "oh" If you mean French: vowels with two dots above them do not change in pronunciation. The dots just mean that the vowel is separate from the previous vowel, such as naïve.
funf... but the 'u' has the two dots above it
No, you are not.
