Issue With Korean translation of Upp Linux application
type: item
description: Hello, We are having difficulty with our app displaying Korean characters. We have followed the directions given here to others: http://www.ultimatepp.org/forums/index.php?t=msg&goto=43 537& We did a copy/paste of the Korean text into t file using Theide editor. Initially, it looks like squares before Upp compilation. The build succeeds and Upp changes the text in the t file to hex numbers. However, these don't render as Korean text in the application but continue to look like squares. A screen image is captured as an example. It is attached along with the t file for this project in tar.gz format. The t file line numbers of the four text in buttons are line #7773, #7787, #7419, and #7808. We used Google translate to go from English --> Korean. For example: "Update vT Software" gets translated to "업데이트 VT 소프트웨어" It is those Korean characters that we copy/paste into Theide for further conversion to the hex number sequences. However, all we get from Upp rendering in our application is square boxes. T file encodings and font in Upp are default utf8 and Monospace. P.S. Copy/paste of the same Google translated Korean text into Leafpad editor renders proper Korean text, and not squares. Additional Context: - Host: is Linux Mint 17.2 on Intel architecture - Upp: we are using upp-x11-src-8760 snap-shot Any suggestion regarding this is very much appreciated. --Jeff

description: Appears to be a font problem. In Win32, it works. CJK characters are handled by "replacement fonts". Unfortunatly, identifying which fonts contain which characters is very slow process, so U++ has fixed font tables to accelerate this (in Draw/FontCR.cpp). We will need to add some typical Linux fonts that support Korean. I have identified these fonts in my distro (Mint) to support Korean: "WenQuanYi Micro Hei Mono" "NanumMyeongjo" "NanumGothic" "WenQuanYi Micro Hei", - that fixed problem for me. Anyway, you might want to run this simple utility to eventually find more fonts in your distro that support Korean: #include <CtrlLib/CtrlLib.h> using namespace Upp; GUI_APP_MAIN { ArrayCtrl a; a.AddColumn(); for(int i = 0; i < Font::GetFaceCount(); i++) { DDUMP(Font::GetFaceName(i)); a.Add(AttrText(String().Cat() << AsString(i) << ' ' << Font::GetFaceName(i) << " 업데이트 VT 소프트웨어") .SetFont(Font(i, StdFont().GetHeight()))); } TopWindow w; w.Add(a.SizePos()); w.Run(); } Then, there are bitfield maps in FontCR. You can use uppbox/FontMaps to generate them... (also, it is a nice demonstration why we need these fixed maps - it is pretty slow

description: Mirek, Thank you for responding to the question and the investigative work you did. You said: "...We will need to add some typical Linux fonts that support Korean." Is there a time table for this to happen? Will it be announced as a release or will it show up in a nightly snap shot? If this were available, we would like to make use of it since we have a need for this in our project. Again, thank you for your help. -- Jeff

description: It is in trunk (and thus in nightly build). Anyway, I have added fonts I have on my distro, so if the problem is not fixed for you (unlikely), my previous message contains intructions how to fix it. Mirek

description: Yes, that fixes the Korean character rendering. Thank you for the solution to this. We are so ecstatic about this! And then I was asked: "Can this solution can be back-ported into upp-2007.1 ?" I told them I would look at the code and see. There does not seem to be a list of language character fonts in upp-2007.1 and so I don't know how to do that. Is there a way that we can back-port the functionality for rendering Korean characters into upp-2007.1 ? -- Jeff
