I have come across with two symbols (that is † and ⁜ in wiktionary) but I don’t know what they mean. Here is the link: https://en.m.wiktionary.org/wiki/子 Note: someone has commented that if I can access the computer web browser I can get the usage of them. Unfortunately, I don’t have a computer so I updated the topic and deleted the previous one.
You can see the meaning on the site that is intended for the destop computer:
†: Obsolete sense in Modern Standard Chinese—may be preserved in fossilised compounds and expressions or other varieties of Chinese.
⁜: Obsolete sense as a 'stand-alone character' in modern standard Chinese. May be preserved in compounds and idiomatic expressions.
