The following are a list of restrictions for product and option titles.
Emojis and non standard symbols are not allowed as part of the title text
and will be stripped out.
While there is no hard limit on the characters count and effective limits
can depend as characters are very different in width. It is recommended to
limit titles to 50 characters though longer titles will be accepted.
If there is only a single option, the option title may be the same as the
product title. If multiple product options are presented, the title must be
unique to the option.
