|
|
* 1) as far as I know, you can't select font sets with the
|
|

|
|
*
|
|
* 2) if you use a font set, the text to be drawn must be a
|
|
* multi-byte string in the appropriate locale, but
|
|
* Ethereal does *NOT* guarantee that's the case - in
|
|
* the hex-dump window, each character in the text portion
|
|
* of the display must be a *single* byte, and in the
|
|
* packet-list and protocol-tree windows, text extracted
|
|
* from the packet is not necessarily in the right format.
|
|
*
|
|
* "Doing this right" may, for the packet-list and protocol-tree
|
|
* windows, require that dissectors know what the locale is
|
|
* *AND* know what locale and text representation is used in
|
|
* the packets they're dissecting, and may be impossible in
|
|
* the hex-dump window (except by punting and displaying only
|
|
* ASCII characters).
|
|
*
|
|
* GTK+ 2.0 may simplify part of the problem, as it will, as I
|
|
* understand it, use UTF-8-encoded Unicode as its internal
|
|
* character set; however, we'd still have to know whatever
|
|
* character set and encoding is used in the packet (which
|
|
* may differ for different protocols, e.g. SMB might use
|
|
* PC code pages for some strings and Unicode for others, whilst
|
|
* NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
|
|
* or one of the EUC character sets for Asian languages, or one
|
|
* of the other multi-byte character sets, or UTF-8, or...).
|
|
*
|
|
* I.e., as far as I can tell, "internationalizing" the packet-list,
|
|
* protocol-tree, and hex-dump windows involves a lot more than, say,
|
|
* just using font sets rather than fonts.
