Package: uni2ascii
Version: 3.9-1
Severity: normal
Tags: patch
uni2ascii fails if a read returns a partial result in the middle of a
multi-byte UTF-8 sequence. This only happens if the UTF-8 sequence is
at least 3 bytes long, because of the detailed logic. Here's a test
case:
------------------------------------------------------------
[EMAIL PROTECTED]:~$ (echo -ne '\344\270'; echo -e '\200') | uni2ascii
0x4E00
1 tokens converted out of 2 characters
[EMAIL PROTECTED]:~$ (echo -ne '\344\270'; sleep 2; echo -e '\200') | uni2ascii
Truncated UTF-8 sequence encountered at byte 0, character 0.
------------------------------------------------------------
The byte sequence '\342\270\200' is a single UTF-8 sequence. In the
first command, with no pause, the read returns the expected result.
In the second command we insert a pause between the 2nd and 3rd bytes,
with a resulting spurious error message.
(The bug was found by Chung-Chieh Shan, cc:ed.)
Patch attached. I note that the file patched, Get_UTF32_From_UTF8.c,
is written by Bill Poser, who is not listed as the author of
uni2ascii; perhaps this file came from some other package, and the
patch should be passed upstream?
Peace,
Dylan Thurston
