Hi,
a year ago, there was a discussion on this list about Encode not
recognizing "TIS-620" as alias for "iso-8859-11":
http://nntp.x.perl.org/group/perl.unicode/1656
In the latest release of Encode::Alias (1.38 from Encode 1.9801,
included in Perl 5.8.2-RC1), "TIS-620" will still fail as a valid
encoding name, although that is still the only Thai character-set name
approved by IANA. So why not applying that simple patch to
Encode/Alias.pm:
# Alias.patch:
176c176
< 'tis620' => 'iso-8859-11',
---
qr/tis[-]?620/i => '"iso-8859-11"',
patch -b Alias.pm Alias.patch
best,
rob.
