+ * generic/tclIO.c (WriteChars): Fix for SF #506297, reported by
+ Martin Forssen <ruric@users.sourceforge.net>. The encoding
+ chosen in the script exposing the bug writes out three intro
+ characters when TCL_ENCODING_START is set, but does not consume
+ any input as TCL_ENCODING_END is cleared. As some output was
+ generated the enclosing loop calls UtfToExternal again, again
+ with START set. Three more characters in the out and still no
+ use of input ... To break this infinite loop we remove
+ TCL_ENCODING_START from the set of flags after the first call
+ (no condition is required, the later calls remove an unset flag,
+ which is a no-op). This causes the subsequent calls to
+ UtfToExternal to consume and convert the actual input.
