Diaeresis (known as tréma in French) and umlaut both employ the same character. But there is a difference of use between diaeresis and umlaut. Letters with umlaut stand for completely different sounds than their non-accented counterparts. For example in Swedish Oo represents /u/ while Öö represents /ø/. Diaeresis on the other hand does not change the sound value of a letter, but instead marks that a vowel is not part of a diphthong or digraph. Both are also known under the general name trema.

The diaeresis and umlaut characters have different origins. Diaeresis was borrowed from the Greek alphabet,[1] while umlaut began as a small e placed on top of Aa, Oo or Uu. This e then later evolved into the same shape as diaeresis.[2]

Uses of Diaeresis or Umlaut

Central vowel Moro Ëë /ˈəː/ This letter represents a "long or stressed ‘ə’",[3] but the phonemicity of it is contested.[4] The orthography for Moro did not have capital letters originally.[3]
Change of place of articulation Malagasy N̈n̈ /ŋ/ This letter is used in some dialects. It may optionally be replaced by Ññ or Ng ng.[5] Note that N̈n̈ is not a precomposed letter.
Front version of back vowel (Ää is included here, even though its unaccented version is not a back vowel in all of these languages) Estonian Ää /æ/, Öö /ø/, Üü /y/
Finnish Ää /æ/, Öö /ø/ Usage borrowed from Swedish.
German Ää /ɛ/, Öö /ø/, Üü /y/ The umlaut evolved from the letter e in the digraphs ae, oe and ue.

Mandarin (Pinyin romanization) Üü /y/, Ǖǖ /y˥/, Ǘǘ /y˧˥/, Ǚǚ /y˨˩˦/, Ǜǜ /˥˩/ Üü without tone markings may stand for the so called neutral tone,[6] or it is simply due to no tone marks being used in the given text.[7] Note that these tone values are based on the Beijing dialect.[8]
Slovak Ää /æ~ɛ/ [æ] is dialectal pronunciation, with most speakers merging it with the phoneme /ɛ/ or /a/.[9]
Swedish Ää /ɛ/, Öö /ø/, Üü /y/ The umlaut evolved from the letter e in the digraphs ae[10] and oe.[11] Üü is not really a part of the Swedish alphabet, but is regularly used in some loanwords and surnames.
Turkish Öö /œ/, Üü /y/ Oo and Uu stand for /o/ and /u/, respectively.
Hiatus Catalan Ïï /i/, Üü /u/ Diaeresis on an Ii or Uu following another vowel marks that the two vowels are in different syllables. Without diaresis, the Ii or Uu would stand for a semivowel.[12]

Digraph disambiguation Lhueslue (external romanization) Qwynegold Ëë /e/ The diaeresis is used when /e/ follows another vowel, and signals that these two vowel letters do not form a digraph. These two vowels are pronounced as a diphthong.[15]

Note that ȷ̈ is not a precomposed letter, but a combination of dotless ȷ and combining diaeresis.
