Re: [agtk-devel] AG Library and UTF-8?

[Haejoong L. <hae...@un...>]

Matthias,

Have you tried 'encoding' option to load the file?

'encoding' option is available for AIF loader.
Here is an example code:

  package require ag
  array set sig {}
  set opt(encoding) UTF-8
  AG::Load AIF timit.xml "" sig opt
  ...

XercesC++ FAQ says that:

Xerces-C has intrinsic support for ASCII, UTF-8, UTF-16 (Big/Small Endian),
UCS4 (Big/Small Endian), EBCDIC code pages IBM037 and IBM1140 encodings,
ISO-8859-1 (aka Latin1) and Windows-1252. This means that it can parse input
XML files in these above mentioned encodings.

Thanks,
Haejoong
