Backport #4869: 2206368128.chr(Encoding::UTF_8) fails strangely

• Status: Rejected

While testing some code which attempted to decode integers into UTF-8 characters, I noticed one number failed to decode:

2206368128.chr(Encoding::UTF_8)
# => RangeError: -2088599168 out of char range

The negative number within the exception makes me wonder if an Integer Overflow is occurring within the M17N code.

This issue has been marked as closed 2 months ago but 1.9.2p290 is
still showing the issue.

Did this get missed for p290 or was it planned for a later release?

$ ruby1.9.2 -v -e 'p 2206368128.chr(Encoding::UTF_8)'
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0]
-e:1:in chr': -2088599168 out of char range (RangeError) from -e:1:in

'

Thanks,
Brian

fixed.
