[Bug 1940283] Re: Misleading Error: Invalid character '"'

[Dirk Zimoch via Core-talk <core-talk at aps.anl.gov>]

Tabs at the beginning or end of the string give even stranger messages:

info(TAB, "a	")
info(TAB, "	b")
Error: Invalid character '"'
 at or before """ in path "."  file "test.db" line 3
Error: Newline in string, closing quote missing
Error: syntax error

info(TAB, "	")
Error: Invalid character '"'
 at or before """ in path "."  file "test.db" line 3
Error: Invalid character '"'
Error: Invalid character ')'
Error: syntax error

Title:
  Misleading Error: Invalid character '"'

Status in EPICS Base:
  New

Bug description:
  When using a tab character in a field, EPICS 7 prints a misleading
  error message, not hinting at the tab but at the closing(?) quote.

  Example 1:  field(DESC,  "a	b")
  Example 2:  info(TAB,  "a	b")

  Error: Invalid character '"'
   at or before """ in path "."  file "..." line ...

  
  BTW: Is there a reason why I cannot use a tab in my (info) fields?
