"PCDATA invalid Char value" error

[IndrajeetPatil]

If I try to spell check this file, I get the following error:

> spelling:::spell_check_file_md("README.md")
Error in read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html,  : 
  PCDATA invalid Char value 27 [9]

I tried to debug this further, but couldn't manage to find the offending text. If it's of any help, this is traceback I see:

> traceback()
7: read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html, 
       options = options)
6: read_xml.character(md)
5: xml2::read_xml(md)
4: xml_find_all(x, "//namespace::*[name()='']/parent::*")
3: xml2::xml_ns_strip(xml2::read_xml(md))
2: parse_text_md(path)
1: spelling:::spell_check_file_md("README.md")

Also, here is my session information:

Can no longer reproduce this, so closing this issue.

Fwiw, I got this error on a file that had written out a bunch of ANSI highlighting:

[90m---
[39m[32mtitle[39m[90m:[39m Notebook Title
[32mauthor[39m[90m:[39m Author Name
[32mdate[39m[90m:[39m |
  `r knitr::inline_expr('format(Sys.time(), "Updated on %A, %B %d, %Y %I[90m:[39m%M %p")')`
[32msite[39m[90m:[39m bookdown::bookdown_site
[32mlink-citations[39m[90m:[39m true
[90m---
[39m

Maybe this will help someone else in the future.

while retrieving the results am getting as Error in read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html, :
PCDATA invalid Char value 27 [9]
How to debug this?
