Questions tagged [trailing-whitespace]

Use this tag for questions related to trailing whitespace characters.

Trailing whitespace characters can be presented/rendered in a way that is not distinguishable from the actual end of the data. This can lead to issues if the data presented to the user differs meaningfully from the actual data.

  • trailing whitespaces in folder names
  • trailing whitespaces in string inputs
  • handling of trailing whitespace: preservation vs. omission
  • preservation of the correct whitespace as different whitespace characters may be displayed in the same way

While SPACE and TAB may be the most common whitespace characters, the Unicode Character Database (source) lists 25 different characters classified as "White_Space":

0009..000D    ; White_Space # Cc   [5] <control-0009>..<control-000D>
0020          ; White_Space # Zs       SPACE
0085          ; White_Space # Cc       <control-0085>
00A0          ; White_Space # Zs       NO-BREAK SPACE
1680          ; White_Space # Zs       OGHAM SPACE MARK
2000..200A    ; White_Space # Zs  [11] EN QUAD..HAIR SPACE
2028          ; White_Space # Zl       LINE SEPARATOR
2029          ; White_Space # Zp       PARAGRAPH SEPARATOR
202F          ; White_Space # Zs       NARROW NO-BREAK SPACE
205F          ; White_Space # Zs       MEDIUM MATHEMATICAL SPACE
3000          ; White_Space # Zs       IDEOGRAPHIC SPACE
