Description

[You will note this is my first Ticket. Please have patience if I have made any mistakes. As far as I can tell this is not a duplicate ticket...]

Saving: Add unicode data to a shapefile through the user interface either by
1) using "Open table" and entering the data in the table, or by
2) using "Capture Point", adding a point and entering the data

Enter data that is non-Ascii (e.g. ŋɪʃ)
Set the label to be data-defined.

If the point has not yet been saved to the database the Unicode characters will appear correctly in the labels. After saving all the non-Ascii characters will change to question marks (?).

Loading:
1) Create a shapefile and close QGIS
2) Change a database file to be encoded in Unicode and enter a few non-ASCII characters (I do this with OpenOffice Calc by a) copying to a new file, b) saving as dbf in UTF-8 encoding, c) cosing OpenOffice and d) renaming the new file with the original name).
3) Open QGIS. The shapefile will load and show the ASCII characters (which are a subset of Unicode), but the Unicode only characters will be interpreted as if ASCII.

I'm not familiar with the Shapfile specifications, but I'm surprised that I can't save Unicode data.

I'm using Windows XP, but I assume this is true for all platforms and have thus selected "ALL".
I'm testing on version 0.11.0 but assuming it affects the HEAD as well.

This problem does not affect QGIS 1.0 preview1 for Windows. I modified a field in a shapefile adding non-ASCII characters (àòè§ç), saved edits and reopened the table. They are all correctly displayed.

Anyway, if I open the dbf file with OpenOffice or Excel, the characters are correctly displayed if I choose Western Europe (ISO-8859-15/EURO) or (Windows-1252/WinLatin 1). It doesn't work with UTF-8 nor Wester Europe (DOS/OS2-850/International) encoding, the latter is OpenOffice default choice.

I work on Windows XP home with an Italian keyboard layout.

Please try it again with a Unicode encoding, such as UTF-8.

Here are some examples you can cut and paste to try:

ポイント　日本語 (Japanese)

ŋʃtooɳɱmɱ (IPA)

Thanks!

#3 Updated by cdavilam - over 15 years ago

If I select utf-8 encoding when I load a shapefile into a qgis project, non ASCII characters are correctly displayed, but if I close and reopen qgis, next time I open the project, non ASCII characters are wrong and I have to remove the layer and reload it so that they are displayed properly.

Shouldn't QGIS save the encoding of the layer as it was loaded first time?

#4 Updated by zachariahyoder - over 15 years ago

While implementing saving the encoding of a file...

Please add an option in New Vector Layer dialog to choose the encoding when first making a new vector/shapefile. (Layer -> New Vector Layer -> New Vector Layer dialog)

It seems the user is currently not given a choice.

P.S. A big thank you to the people who spend their time to fix bugs like this!!!

I have repeated the steps described by cdavilam and it works for me in both 0.11.0 and 1.0.0 preview II (which is called .preview1 in the about window)

See #1496 "setting the encoding..."

Replying to [comment:5 zachariahyoder]:

I'm running QGis 1.0.1-Kore (reported by QGis), installed on Windows using the OSGeo4W installer, and this bug seems to exist still:

When adding an ESRI Shapefile containing UTF-8 data as a new layer to a project, the labels are shown correctly. Saving the project, closing the program, restarting it and reopening the project, non-ascii characters in the layer labels are not shown correctly.

I did look through the saved project file, and the string "utf" does not appear anywhere there, definitively not below the layer definition, so it seems, that at least in this version, the layer encoding is NOT saved in the project files.

Provider encoding is now saved to and read from project file in (backport to 1.0 follows soon). I don't have any japanese characters to test, for my german special characters it works now.
