Category:CS1 errors: invisible characters

This is a tracking category It is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

This is a tracking category for CS1 and CS2 templates that have parameter values that contain invisible or non-printable characters.

<char> character in |<param>= at position n

This error is reported for citations with parameter values that contain invisible or non-printable characters known as control characters; the error includes the position at which the character can be found. Module:Citation/CS1 detects parameter values that contain any of these characters:

replacement character, U+FFFD

hair space, U+200A

zero width space, U+200B

zero width joiner, U+200D (January 2018 note: text in Sinhalese reports this error due to a bug; a fix will be deployed in the first quarter of 2018)

soft hyphen, U+00AD

horizontal tab, U+0009 (HT)

line feed, U+0010 (LF)

carriage return, U+0013 (CR)

delete character, U+007F (DEL)

C0 control, U+0000–U+001F (NULL–US)

C1 control, U+0080–U+009F (XXX–APC)

To resolve invisible-character errors, remove or replace the identified character. Because these characters are mostly invisible, the error message identifies the character's position in the parameter value counted from the left. Space characters between the assignment operator (the '=' sign) and the parameter value are not counted.

<name> stripmarker in |<param>= at position n

Strip markers are special sequences of characters that MediaWiki inserts as a place-holder for certain xml-like tags. These tags include <gallery>...</gallery>, <math>...</math>, <nowiki>...</nowiki>, <pre>...</pre>, and <ref>...</ref>. The strip markers are replaced with content before the final page rendering. The module ignores math and nowiki strip markers.

To resolve strip marker errors, remove or replace the identified tag. The error message identifies the strip marker's position in the parameter value counted from the left. Space characters between the assignment operator (the '=' sign) and the parameter value are not counted.

Strip marker errors can also be caused by unsupported additional text or templates in parameter values (e.g. {{ISBN}} in |title=). Resolve the problem by moving the extraneous text outside of the citation template or by removing the extraneous text or template markup, as appropriate.
