This isn't a problem for Chinese names but I gather it's a problem for many foreigners with apostrophes, Jr., Sr. III, etc in their names. Hopefully they will fix this. As an aside, I can use the exit machines at the land border crossings in Shenzhen as there is obviously no ticket to match names with.
