Sure, but the subtype only tells us there is an automatic disc (=2), not the glyph (which may be changed with \exhyphenchar). May I assume there is only a single glyph in the 'replace' node list (namely, the char = \exhyphenchar when the node list was built)?
yes because the character code only codes one character
Thank you for the confirmation. This makes fixing babel trivial. Javier
