| Title: | Tcl 9: "illegal byte sequence" ?! | |||
| Type: | Bug | Version: | 9.0a4, trunk | |
| Submitter: | pointsman | Created on: | 2022-12-12 23:44:57 | |
| Subsystem: | 25. Channel System | Assigned To: | jan.nijtmans | |
| Priority: | 5 Medium | Severity: | Minor | |
| Status: | Closed | Last Modified: | 2022-12-20 09:46:27 | |

| Description: |
With 252e282cd21b (2022-12-12 06:11:22 UTC)
# Create the test data
package require Tcl 9
set fd [open data.txt w+]
fconfigure $fd -encoding utf-8
puts $fd "A\U10FFFFBCDE"
close $fd
# The data is a valid UTF-8 encoded Unicode string
# in the understanding of Tcl.
# Try to read it
package require Tcl 9
set fd [open "data.txt"]
fconfigure $fd -encoding utf-8 -strictencoding 1 -nocomplainencoding 0
set data ""
while {![eof $fd]} {
append data [read $fd]
}
# Not reached with this test data
puts [string length $data]
close $fd
I get:
error reading "file6": illegal byte sequence
while executing
"read $fd"
("while" body line 2)
etc.
Expected behaviour:
Read the data without raising error.

Branch now merged to core-8-branch and trunk. Closing jan.nijtmans added on 2022-12-19 22:21:28: As there seems no interest to check for noncharacters, remove those checks. See [cbaa5e70167db75b] jan.nijtmans added on 2022-12-13 11:47:09: B.T.W. I know that "illegal byte sequence" is not the best error-message we can think of. But that's a limination of the channel code, that we are restricted to POSIX errors. This one is the closest to the truth. jan.nijtmans added on 2022-12-13 07:59:45: Does [05414ca78462df68|this] clarify the situation? Referring to ticket [084ab982fe], you asked there: > Why do we have the fconfigure -strict mode at all? Apparently, -strict is not the right option for you. | |||
