----------------------------
Yes, all test cases pass on the new version. Thanks for the timely fix.

> Key: LANG-1823
> URL: https://issues.apache.org/jira/browse/LANG-1823
> Project: Commons Lang
> Issue Type: Bug
> Affects Versions: 3.20.0
> Environment: java version "1.8.0_202"
> Reporter: 尹茂椿萱
> Assignee: Gary D. Gregory
> Priority: Major
> Fix For: 3.21.0
>
>
> {{LocaleUtils.toLocale(String)}} claims to strictly validate and convert a
> locale string into a {{Locale}} object. However, it fails to parse certain
> valid locale strings produced by the JDK itself.
> Specifically, some {{Locale}} instances returned by
> {{java.util.Locale#getAvailableLocales()}} produce string representations
> (via {{{}toString(){}}}) that contain a {{#}} character (e.g.,
> {{{}"th_TH_#Thai"{}}}). These strings cannot be parsed by
> {{{}LocaleUtils.toLocale{}}}, resulting in an
> {{{}IllegalArgumentException{}}}.
> This creates an inconsistency where valid JDK locale representations cannot
> be round-tripped through {{{}LocaleUtils{}}}.
> h3. *Steps to Reproduce*
> import java.util.Locale;
> import org.apache.commons.lang3.LocaleUtils;
> public class Repro {
> public static void main(String[] args) {
> for (Locale locale : Locale.getAvailableLocales()) {
> String str = locale.toString();
> try {
> Locale parsed = LocaleUtils.toLocale(str);
> } catch (Exception e) {
> System.out.println("FAIL: " + str);
> }
> }
> }
> }
>
> ----
> h3. *Observed Behavior*
> Example failing output:
> {{FAIL: th_TH_#Thai}}
> {{LocaleUtils.toLocale("th_TH_#Thai")}} throws
> {{{}IllegalArgumentException{}}}.
