* See #3858 * We need to pass a java.lang.String to TRegex, in this case we can pass it as raw bytes since we also pass the encoding name to TRegex. * Remove the UnsupportedCharsetException catch clause as no Charset should be involved in this conversion since the migration to TruffleString.

Need to look at a new run now that #3859 got merged |

We noticed in ruby/net-imap#470 that some Regexp are not Regexp.linear_time? on TruffleRuby, but they should be.
See the output in CI of that PR/repo, e.g. https://github.com/ruby/net-imap/actions/runs/14917675208/job/41906831286#step:5:54
One specific I noticed is
/[\x80-\xff\r\n]/n, which I have a fix for.(cc @nevans)
