These Modifiers are used so texts inserted into a template are encoded in a certain way; Most transports like XML have a list of characters to transfor to preserve their meaning.

uses StrEscAppend Mode 0

The relevant chars of the text is transformed into HTML-entities so they can be used by a client application. If you want to show the text “a<b” in a textarea it will become:

a<b

uses StrEscAppend Mode 2

If the linewraps of your text should also be converted into HTML linebreaks, use this escaper.

a
b

will become

a<br/>b

uses StrECMAEscAppend

Escapes all characters that have a meaning in Javascript strings; ' and \ are Protected (since webcit implicitely converts everything to utf-8, you don't need to take care of that):

'a\nb'

will become

\'a\\nb\'

uses StrHtmlEcmaEscAppend

Add html escaping to J; some Parsers are also vulnerable to other chars; use this to get rid of some more of the dangerous chars.

uses StrBufUrlescAppend

Transform all chars that have a meaning in HTTP-URLs into %HexCode; use this if you want to add encoded parameters

a b c

will become

a%20b%20c

a-z
A-Z
0-9
