Roberta Sets 136zip Fix - Wals

This specific system error occurs when trying to process pre-packaged dataset zip containers (historically cataloged as payload 136.zip or split chunk index 136). The tokenizer corrupts categorical sets due to missing escapes or hidden carriage returns embedded within the dialect mapping strings. Root Causes of the Tokenizer and Zip Set Collision

This update addresses a critical issue in the wals_roberta_sets_136.zip archive. Previous versions of this file contained corrupted or misaligned data splits for the RoBERTa-based WALS processing pipeline (set 136). The fix includes:

Step 2: Harmonize the RoBERTa Tokenizer Vocabulary
