Android Question [solved] how to use the List.Sort ??? (issue with utf-8 byte order mark from notepad editor)

MarkusR · Mar 21, 2018

i have a textfile in utf-8 and this code but the list is not sorted. (7.80)
i put a A at top of the file and a Z an the end.

B4X:

    Dim problems As List = File.ReadList(File.DirAssets,"problems.txt")
    problems.Sort(True)

    Dim i As Int
    For i = 0 To problems.Size-1
        Log(problems.Get(i))
    Next

it seems there is a sort bug with utf-8
if me using the file in Ansi the umlauts [äöü] are wrong displayed in app.

It might depend on your locale settings.

interesting,thanks for this hint.
but me thought b4a based on utf-8, the first char is just A-Z or its better to use unicode text files?

Can you upload the text file? Is it encoded with UTF 8?

here it is, it is a list of IT issues i saved with notepad in utf-8.

You should never use notepad.

I've talked about this exact issue in one of the first videos. Your file is encoded in UTF8 with BOM.
Use a decent text editor such as Notepad++ and encode it in UTF8 without BOM.

Or skip the first character.

thank you, i put an empty row first. we faced this BOM issue also in batch files not long ago.
i watched all of your videos, i will watch again ... its part of videos "Strings"

Doesn´t change anything if you still uses BOM. The solution is NOT TO USE BOM inside the File.

How are you creating this file? Programatically?

correct, at least with a dummy line my first entry with A is at top in my sort
it was just a manual input in editor. i will make a feature request at ms.
i can also use notepadd++ where i make this app.
maybe i will put my lists into a sqllite db later on.

As written by Erel you should NEVER use Editor. Use Notepad++ instead.

i avoid generally downloading apps from web that use admin permissions at install. and without permissions they have my user permissions.
why i can not open/edit this textfile in the ide editor?
if you drag a textfile on this ide link it got the filename and its ignored. the open menü not support .txt

Did you see this in Notepad++'s download section?

Notepad++ zip package 32-bit x86: Don't want to use installer? Check this one (zip format).

Notepad++ 7z package 32-bit x86: Don't want to use installer? 7z format.

Same goes for the 64 bit version.
