How to view Chinese text?
Feb 12th, 2008, 10:00am  
I'm pulling Chinese content from MySQL.  I'm certain the data is properly stored in MySQL.  I'm unable to see the Chinese characters when I use text().  I see "??" in the console when I use println().  I'm running English Win XP.  

Do I need to use a unicode font?  Do I need to use some sort of String processing for UTF-8?

I've also tried to hardcode a String with Chinese text, but that results in the same "??" problem.  
String cn = "chinese text here";

I also noticed that unicode is not saved in a pde file.

What am I missing here?  I'm sure that this problem has been seen by many users.

thanks!

- make sure you check "All Characters" when creating your vlw font in processing

- check that the console-font supports the chars you need (see preferences.txt -> "console.font=...")

- try loading utf-8 text from a file (since rev 134 processing reads files as utf-8) and println()

- check your java-log (does winxp have that?) to see what ends up in there when you println()

Thanks for the info.  Here is what I've done so far without any success:

1.  "make sure you check "All Characters" when creating your vlw font in processing."

I created a vlw font from MS_Song-20, which is an installed Chinese font on Win XP.  The vlw file is 7.35 MB and results in a Out of Memory error when I run the applet.

2.  "check that the console-font supports the chars you need (see preferences.txt -> "console.font=...")"

Changed to MS_Song, but the console still prints "??".

3.  "try loading utf-8 text from a file (since rev 134 processing reads files as utf-8 and println() ".

I'm running rev 135 Beta.  I tried to read from a text file using code from this entry  http://processing.org/discourse/yabb_beta/YaBB.cgi?board=OpenGL;action=display;num=1176716495;start=0#0.  The console printed "??", the sketch rendered boxes...which is more than I saw before.

4.  "check your java-log (does winxp have that?) to see what ends up in there when you println()".

I don't know where to locate the java log file.  I'll look around...

1. that's because you'll have a ridiculous number of characters and it's trying to load them all as images. use createFont() in your code and specify a charset:
http://processing.org/reference/createFont_.html

1b. read the troubleshooting page on OutOfMemoryErrors.
http://processing.org/reference/troubleshooting/index.html

2. the java console isn't any good at handling encodings properly, so ?? in the console is not a good indicator of whether things are working. use the text() function and see what results you get.

3. see #2.

4. the location of the java log for windows is also described on the troubleshooting page.

Ok, I figured it out.

1.  Install the East Asian Language files.  I downloaded them from BitTorrent.

2.  Use createFont(); and choose a font from the East Asian language pack.  Don't use the create font tool to create a .vlw because it eats up memory.

PFont sysFont= createFont("mingliu", 18);

3.  You can use String cn = "chinese text here";  No additional UTF-8 casting is necessary.  I'm pulling the Chinese text from MySQL.  Hardcoded Chinese text may be problematic.

4.  I can't get the console to prinln() Chinese text, but I can live without it.
