Description of problem:
when using the cs_CZ.UTF-8 locale in LC_CTYPE category, iconv cannot encode
non-ascii data to the "us-ascii//TRANSLIT" encoding.

Version-Release number of selected component (if applicable):
glibc-common-2.4-8

How reproducible:
100%

Steps to Reproduce:
1. LC_CTYPE=cs_CZ.UTF-8 iconv -f utf-8 -t us-ascii//TRANSLIT <<EOF
á
EOF
# the above was lowercase "a" with acute above character
  
Actual results:
The character "á" is transliterated as "?".

Expected results:
The character "á" should be transliterated as "a".


Additional info:
Pavel Kankovsky suggested that the following lines should be added to
the locale definition, to the LC_CTYPE section:

  translit_start
  include "translit_combining";""
  translit_end

I don't know the transliteration rules for the English language, but the en_US
and en_GB locales should probably be changed as well For example, the cy_GB
locale contains the above section as well.
