eeschema: remap fail on symbols with deprecated chars in name

[Sergey A. Borshch]

Previous kicad version allow chars like slash ('/') in symbol name. After some upgrade all such chars was deprecated and silently(!) replaced with underscore in library files. Seems like remap procedure on opening old schematics replaces slash by underscore but unable to find translated name in libraries and creates copy from cache-lib in rescue library, although symbol with translated name exist in global library. Example: symbol 74HC595/SO in old schematics remaps to project_name-rescue:74HC595_SO while 74HC595_SO exist in global library.

This is not a bug unless the symbol is not showing up in your schematic. This had to be done in order to support the new library ID which cannot handle ':' and '/' characters in symbol names. It's been this was since 5.0.0 was released. Once the new schematic and symbol library file formats are implemented, this issue will be resolved.

Yes, I understand that '/' character is deprecated. I don't understand why it is impossible to search modified name (e.g. name with '/' replaced by '_') in library?

[Sergey A. Borshch (sb-sf)]

It's quite annoying to search whole schematics for all elements mapped to project_name-rescue lib and manually replace project_name-rescue to actual global lib name.
