Sure - please fetch http://md.bts.sk/telx/ct1.ts

Select teletext page 898 - the test picture.
It should look like this:

http://www.ceskatelevize.cz/teletext/index.php?page=898&ver=&channel=

The capital letters are (mostly) OK, only "Ť" is missing.
However the small special characters at rows 08 and 09 are completely
wrong.

Those characters are transmitted differently - the capitals which require
advanced teletext capabilities work almost fine.

But the small letters are those basic national subsets mentioned in
modules/codec/telx.c:
 
static const uint16_t ppi_national_subsets[][20] =
{
  { 0x0023, 0x016f, 0x010d, 0x0165, 0x017e, 0x00fd, 0x00ed, 0x0159,
    0x00e9, 0x00e1, 0x0115, 0x00fa, 0x0161 }, /* czech,slovak  ,011 */



   With kind regards,
