Maybe you can also try asking guys in 中文论坛 / 中文論壇（简体 / 繁體）

This seems to be related to fonts.
Apparently very few fonts on my system are able to display all chinese characters. I found this one that does it partially:

Would be interesting if you can post here a font that is known to display it all?

Some DBCS-related issues, I found in FreeCAD. (0.18.4/ 0.19pre, Win10x64)

1. DraftWB, dAnno and dLabel print Chinese characer in UTF-16 code (not as Chinese font glyph).
2. DraftWB, Dimension>Overide, doesnot print Chinese text on viewport.
[SOLVED] 3. DraftWB, ShapeString donnot apply Chinese font filename (not font family name).
4. DraftWB, dAnno save Chinese text as messy code, and print nothing on viewport.
ps. workaround: edit dAnnot text property, and input Chineset text again. This time dAnno can save Chinese text correcty, and print UTF-16 code on viewport. While dLable has no this issue.

5. On Windows10x64, only Arial (arial.ttf) and Courier (cour.ttf) can be apply to DraftWB's dAnnno/dLabel/Dimension. Fallback font is FreeCAD's internal font. All these fonts (arial/courier/internal) donnot support DBCS/CJK.

6. Preferences> Genereral> Editor> Family, donnot save Chinese font family name in "user.cfg" file.

ShapeString donnot apply Chinese font filename (not font family name).

In the python console, can you try the following for me please?

Code: Select all

>>> import Part
>>> myCJKString = "something in CJK chars"
>>> myCJKFont   = "CJKName.ttf"        #real CJK font file please! 
>>> ws = Part.makeWireString(myCJKString, myCJK, 100.0, 0.0)

This will probably fail(???). It doesn't look like makeWireString can handle unicode file names properly and this will confirm if there are changes needed here.

Thanks,
wf

@yorik, some Chinese fonts download.

1. Google DroidSansFallback (developed for Android, opensource)
https://packages.debian.org/sid/all/fon ... k/download

2. Google Noto Sans/Serif CJK (successor of DroidSansFallback, opensource)
https://www.google.com/get/noto/

3. HYSWLongFangSong (suitable for Chinese CAD drawing, unkown copyright)

Thank you, wandererfan.

There is a typo in your code, in line 3, "myCJK" should be "myCJKFont". I fixed it and made 3 test.

Test 1, English font with English filename
(before test, get fontfile full path "C:\Windows\Fonts\cour.ttf")

Code: Select all

import Part
myCJKString = "ShapeString test on English font filename."
myCJKFont   = "C:\Windows\Fonts\cour.ttf"
ws = Part.makeWireString(myCJKString, myCJKFont, 100.0, 0.0)

result: nothing happend to console and viewport

Test 2, Chinese font with Chinese filename
(before test, get fontfile full path "C:\Windows\Fonts\汉仪长仿宋体.ttf")

Code: Select all

import Part
myCJKString = "ShapeString的测试：字体文件的中文名。"
myCJKFont   = "C:\Windows\Fonts\汉仪长仿宋体.ttf"
ws = Part.makeWireString(myCJKString, myCJKFont, 100.0, 10.0)

result: nothing happend to viewport, but error msg in console

Code: Select all

Traceback (most recent call last):
  File "<input>", line 1, in <module>
Part.OCCError: Font file not found: C:\Windows\Fonts\汉仪长仿宋体.ttf

Test 3, Chinese font with English filename
(before test, rename "C:\Windows\Fonts\汉仪长仿宋体.ttf" to "C:\Windows\Fonts\HYSWLongFangSong.ttf")

Code: Select all

import Part
myCJKString = "ShapeString的测试：字体文件的中文名。"
myCJKFont   = "C:\Windows\Fonts\HYSWLongFangSong.ttf"
ws = Part.makeWireString(myCJKString, myCJKFont, 100.0, 10.0)

result: nothing happend to console and viewport

ps.
Chinese font file, named "汉仪长仿宋体.ttf" (same as my above post to @yorik).

Great, thanks. This means we need some changes to makeWireString and the C++ routines that support it.

To see the result of ws = Part.makeWireString, add "Part.show(ws)" .

Is everybody experiencing this problem running Windows and version18?

I thought I'd just run some checks before making code changes, and on freecad-daily CJK in the filename doesn't seem to be an issue for ShapeString or makeWireString.
