RE: [xsl] Upper ASCII chars

[Jay Burgess <jburgess at delanotech dot com>]

You guys are making this issue bigger than I need it to be... :)

I'm simply testing that if a user enters a character in the range 128-255 
as part of their data, that our software doesn't do anything weird to 
it.  It's not relevant which codepage was in use when the data was entered, 
as we simply pass the binary value of the character through (or at least 
that's what the tests are supposed to validate). When the user enters 0x9B, 
etc., it'll be the character that they want it to be.

But thanks for the comments.

Jay

As far as I can tell, when someone says "upper ASCII" it is foretelling of
a character encoding problem : it usually means "8-bit characters outside
of ASCII, whose encoding has not been specified". For example, what
character is at 0x9B ? For the three most commonly encountered
codepages on the PC :
IBM 850 : o slash (ø)
IBM 437 : c slash (¢)
windows 1252 ('ANSI')/latin-1 : right single guillemet (>)

I hope for you that your ssi parser will be lucky in its choice of
codepages,
particularly if you are under Windows since windows uses different
codepages for the UI ('ANSI') and for filenames ('OEM').
