Chinese Character Data

Administrator

Can I e.g. paste Chinese characters from a web page and save as data? I don't need to be able to use Chinese characters for code. I see pasting creates a wide string but the characters do not display. I assume this is because my font does not support them, but in the Settings Browser I only see 3 choices on Mac, none of which seem to display them.

Cheers,
Sean

This may be due to FreeType not really being loaded? Try unchecking and then checking again "Use free type...".

But apart from fonts, CJK content should work.

However I don't quite understand why would I need to change font so CJK characters are displayed.

Because no matter what font I pick, there will be language whose characters are not supported...

and why do I need to select the font in the first place? My linux terminal has DejaVu Sans Mono font and yet it displays CJK characters just fine,

so surely we can do better than a stupid urxvt terminal?

Good questions!
Does FreeType manages fonts? Selecting an alternate font when the asked
glyph is absent?
No idea, and I am curious to know how it is managed at the OS level.

For DrGeo, at startup time, I load different font depending on the
language of the OS host, about copy pasting chinese text it does not
work for me. I got unicode values: \u81fa\u5317\u5e02 and not 臺北市.
But may be a problem of my host.

On Linux this is managed system-wide with fontconfig, however I have no idea how it is actually implemented (and thus if Pharo could reuse it or if it would have to implement it on its own).

language of the OS host, about copy pasting chinese text it does not
work for me. I got unicode values: \u81fa\u5317\u5e02 and not 臺北市.

What OS? Because Linux VM by default is NOT set to Unicode, which does cause issues.

in any case,

default font:

CJK-friendly font:

Yes, it should work with the right font:

With DrGeo (Linux Pharo 3.0 based with utf8 encoding set in the VM
parameters) with chinese GUI, copying pasting in the workspace does not
work.

Thanks to all! Yes, changing the "default" font to e.g. "Arial Unicode MS" did the trick for e.g. GT Inspector display, and changing the "code" font to same made pasting work as expected.
