Description Aron Budea 2016-10-06 13:42:19 UTC 
Unicode characters can be input in Windows via hexadecimal codes as described here: https://en.wikipedia.org/wiki/Unicode_input#In_Microsoft_Windows
By default the input is decimal (can be changed to hexadecimal in registry).

In bug 101962 one of the "ü" characters is 0x75 + unicode binding 0x0308. In decimal this is 117 + 776.

In WordPad typing Alt+117 yields "u", then adding Alt+776 yields "ü".
In Writer typing Alt+117 yields "u", then adding Alt+776 yields "u◘".

Behavior is the same since 3.3.0.
The same issue might exist in other OSes, but I haven't checked.

Interesting detail, this doesn't work in Firefox and Vivaldi browsers, either.

Another detail, Dennis found these links on Unicode input in Windows:
http://www.irongeek.com/alt-numpad-ascii-key-combos-and-chart.html
http://www.fileformat.info/tip/microsoft/enter_unicode.htm

Method 4 on the Fileformat.info link is really nice, typing the following yields "ü" in WordPad: "u0308" then Alt+X.

In LibreOffice it's also supported, but is buggy, and produces "u030U+0038".
On the other hand, "0308" and Alt+X produces a special " character, then hitting left arrow, and typing "u" yields the correct "ü" character.

This didn't work for Dennis, as Alt+X opens Extras menu for him.

Enter U+0075U+0308 and then toggle. Result?

We have implemented our own reliable methods for handling Unicode input.

The LibreOffice Special Character dialog, or

as implemented for bug 73691, if you enter U+0075U+0308 in any LibreOffice module and toggle with <alt>+X, you get the combined ü

The Hex input using Windows number pad is not a reliable means of input. What we provide suffices.

German local uses <Alt>+C for the Unicode toggle.
