[Korea-chapter] Web3D e-Learning SIG Agenda (10-13-2011); Korean font problem details

[Don Brutzman]

Thank you for sending your example Text file Kwan Hee Yoo
and for providing permission to send it to the mail list.

I have attached the file and images as a zip.

X3D-Edit revealed the following problems, all fixed:

- <box/> on line 12 is illegal, removed

- Transitional DTD is no longer recommended since it is not portable
http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#SchemaDTD

- Schema errors found:

- I changed the repeated illegal construct 0-1 to -1, is that correct?

- Multiple occurrences of  DEF='image' are illegal since each DEF
value must be unique.  Removed.

- There is only one kind of <!-- legal XML comment -->
so the stray comment //동영상 which appeared on line 131 was changed to
<!-- 동영상 -->

- similarly on original line 110, //1번 사람 이미지 mpeg 영상 파일

- now all validation errors (from X3D-Edit check-mark button) are cleared

- cleaned up using Canonicalization (C14N) to make source more readable

improved version attached.

BS Contact did not render the Korean characters for me, probably
because I don't have Korean fonts installed on my system.  Many
browsers depend on system fonts because they can be large to
download.

Similar rendering results for InstantReality.

Interestingly I can see all of the Hangul factors fine in the
X3D-Edit source editor pane

I hope you agree that several practices are general and important here:
- valid X3D
- choice of Text and Font default values

Please let me know if this helps, and if you are still able to render
the result with your system.

all the best, Don
