of chars produce in the encoding result. When the flag
TCL_ENCODING_CHAR_LIMIT is set and dstCharsPtr is not NULL, then the
initial value of *dstCharsPtr is taken as the max number of chars to produce.
The limit is imposed in a way that does not require the assistance of the
encoding's driver procs, but the flag is passed on to them in case they
can do better when they know they should. No callers updated yet.
No drivers updated yet.
One difficulty is that this necessarily imposes a pre-translation limit,
and the I/O system has a history of wanting to impose only a post-translation
limit.

Perhaps this is a welcome convenience for some callers, but not for Tcl's
I/O system, which has no need for that. Added a new flag value
TCL_ENCODING_NO_TERMINATE that callers can use to suppress this behavior.
This means buffers don't require so much padding, and a tiny bit of processing
is saved. Update I/O callers to use the feature.

supplied by Mo DeJong to fix [Bug 1516109]. Backport from Tcl
8.5. Mo's description: Clear the TCL_ENCODING_END flag when end
bytes are written. This fix keep this method from writing escape
bytes for an encoding like iso2022-jp multiple times when the
escape byte overlap with the end of the IO buffer.
* tests/io.test: Add test case for escape byte overlap case.

commentary to a piece of code which relies on BUFFER_PADDING to
create enough space at the beginning of each buffer forthe
insertion of partial multi-byte data at the beginning of a
buffer. To explain why this code is ok, and as precaution if
someone twiddled the BUFFER_PADDING into uselessness.
* generic/tclIO.c (ReadChars): [SF Tcl Bug 1462248]. Added code
temporarily suppress the use of TCL_ENCODING_END set when eof
was reached while the buffer we are converting is not truly the
last buffer in the queue. together with the Utf bug below it was
possible to completely bollox the buffer data structures,
eventually crashing Tcl.
* generic/tclEncoding.c (UtfToUtfProc): Fixed problem where the
function accessed memory beyond the end of the input
buffer. When TCL_ENCODING_END is set and the last bytes of the
buffer start a multi-byte sequence. This bug contributed to [SF
Tcl Bug 1462248].
