* UrlEscapeA [SHLWAPI]
*
* Converts unsafe characters into their escape sequences.
*
* The converted string is returned in pszEscaped if the buffer size
* (which should be supplied in pcchEscaped) is large enough, in this
* case the function returns S_OK and pcchEscaped contains the length
* of the escaped string. If the buffer is not large enough the
* function returns E_POINTER and pcchEscaped contains the required
* buffer size (including room for the '\0').
*
* By default the function stops converting at the first '?' or
* '#'. [MSDN says differently]. If URL_ESCAPE_SPACE_ONLY flag is set
* then only spaces are converted, but the conversion continues past a
* '?' or '#'.
*
* BUGS:
*
* None of the URL_ define values are documented, so they were
* determined by trial and error. MSDN mentions URL_ESCAPE_PERCENT
* but I can't find a value that does this under win2000.
* URL_DONT_ESCAPE_EXTRA_INFO appears to be the default which is what
* we assume here. URL_ESCAPE_SEGMENT_ONLY is not implemented
* (value??). A value of 0x2000 for dwFlags seems to escape
* '/'s too - this is neither documented on MSDN nor implemented here.
* For character values that are converted see URL_NeedEscape.
