... Well, my information was not correct.
There are characters > 127 in the file, like "ř", "š"...
Each char = 1 byte, and as I'm using Windows with CP 1250, the characters are displayed correctly.
But I have problem loading them into ConTeXt.
I need to convert the bytes > 127 to UTF sequence, which would be acceptable by ConTeXt.
@Thomas:
The table looks nice but there are no entries for CP 1250 to UTF conversion.
I prepared some tables: character conversion and removal of diacritics (see the attachment);
maybe it would be handful to include them into ConTeXt somehow.
Best regards,
Lukas
