How do I escape Special Characters in Solr's Schema.xml file - solr

How do I replace the special character (/) in the Schema.xml file of solr? I already am replacing the special characters(_ and -) with " " using the solr.PatternReplaceCharFilterFactory.
Or can it be escaped automatically by configuration without the user having to enter the escape character() at the time of querying?
Thanks

Snowflake: How to remove backslash from select query?

There are backslashes in our Snowflake database and I want to replace them with blanks but the replace function is not working. Is there a way to remove backslashes from a string in Snowflake?
Are you escaping the backslashes? The escape character for Snowflake string literals is a backslash, so if you want to replace a single backslash you have to put in two backslashes:
set my_string = 'My string with one \\ backslash'; --Shows how to escape a backslash
select $my_string; --Shows the effect of escaping a backslash, only one shows
select replace($my_string, '\\'); --Remove backslashes, replace with nothing

How to escape apostrophe in nagios contacts config file

There is a user with apostrophe in their name.
Nagios documentation says that semicolon, apostrophes and quotation marks should be avoided but it doesn't provide info about how to escape one if it is name.
I have tried \' , \\', "someo'name", "someo\'name" etc but nagios checkconfig fails every time.
Please let me know what else I need to do.

Escape character in batch file

I am trying to get escape character like below:
C:\\Program Files (x86)\\Java\\jdk1.7.0_25
Here is the code in batch script:
set AGNT_JAVA_HOME=%JAVA_HOME% SET
set AGNT_JAVA_HOME=%AGNT_JAVA_HOME:\\=\\\\%
But the value coming is :
AGNT_JAVA_HOME value is C:\Program Files (x86)\Java\jdk1.7.0_25
Any idea what need to be added here to get the value as first line.
The escape character for batch is ^, not \.
The \ literal does not require escaping.
So all you need is:
set AGNT_JAVA_HOME=%AGNT_JAVA_HOME:\=\\%
But it is safer to enclose the entire SET assignment in quotes, just in case AGNT_JAVA_HOME contains a poison character like &.
set "AGNT_JAVA_HOME=%AGNT_JAVA_HOME:\=\\%"

Windows "type" command displays wrong space between numbers

I'm trying to parse some summary report in batch script. (Summary created by "FPRUtility.bat" which is shipped with "HP Fortify SCA and Apps 4.10").
It has text like "Total for all categories => 9 814 Issues". But when i try to use this line in batch file (using type command, or passing this line to %var% and then using "echo") next text displays:
Total for all categories => 9┬а814 Issues
So as you can see space between numbers was changed to some symbols.
File encoding is UTF-8, if i change it to ANSI "┬а" becomes just "а".
If in any editor i delete space and type new space, then displaying is ok.
Turning on "Show all symbols" or "Show White Space and TAB" options in Notepad++ shows no extra symbols but space.
You could use jrepl (a batch/jscript hybrid script) to replace unicode characters.
FPRUtility.bat | jrepl "\u2013" " "
You need to replace \u2013 to your whitespace unicode character

Querying backslash

I am trying to query a table that has strings with backslash (/). For example strings are:
test
test/test
test4
test5
When I use wild char I do not get "test/test" in the result set. I searched web for including backslash in queries, but couldn't find a solution. Does any one have any idea about this issue?
EDIT:
it is a simple query like:
SELECT * FROM aTable;
I believe that you should escape backslashes. I've needed to do it when I used PHP's echo statement.
You can escape backslashes by typing a backlash before the backslash you want to escape
Like: \\
You might want to also add backticks to the table name
`aTable`, or there;s a chance that it won't work.
