Emmet doesn't expand properly when umlauts are used

[egamma]

Extracted from https://github.com/Microsoft/vscode/issues/4960

• Daten^ is expanded to

<Daten></Daten>

• DatenSätze^ is expanded to

DatenSä<tze></tze>

instead of

<DatenSätze></DatenSätze>

Seems like a bug abbreviation extractor. Figure out if such behaviour is relevant in common use cases

Hi, I'm a user of CudaText and opened a related issue there (See https://github.com/Alexey-T/CudaText/issues/2710)

The funny thing is, the DatenSätze example is working in the latest CudaText. So maybe in the meantime there was a fix somewhere...

Please check the examples given in the CudaText issue, where it looks as if every non-standard letter removes one letter from the abbreviation search string -- can these be reproduced with this current version of Emmet?
