VrtxOmega opened a new pull request, #50948: URL: https://github.com/apache/arrow/pull/50948
Fixes #50893 soundex_utf8 in cpp/src/gandiva/precompiled/string_ops.cc used locale-sensitive isalpha()/toupper() to classify characters. Under non-C locales (e.g. en_US.UTF-8), isalpha accepts bytes 0x80-0xFF as letters, and toupper leaves them past 'Z', so mappings[c] (26-element table, A-Z) is indexed out of bounds. Replace with ASCII-only range checks, consistent with the soundex specification which only processes A-Z. -- This is an automated message from the Apache Git Service.
