| Summary | 0010301: All types of non breaking spaces should be displayed as red underscore in story editor | ||||
| Description | In story editor, CTRL+SPACE = non breaking spaces are displayed as red underscore. Thats perfect. But all other spaces are displayed as spaces. Proposition : ALL different types of non breaking spaces should be displayed as red underscore aswell : "espace fine", "moyenne" and more. | ||||

According to unicode line breaking rules, thin space and hair space all provide break opportunites and hence cannot be considered as non breaking spaces. See http://unicode.org/reports/tr14/#BA. You can find the non breaking space here: http://unicode.org/reports/tr14/#GL Some other chars also prevent line breaking : http://unicode.org/reports/tr14/#WJ However zero-width no-break space (0xFEFF) usage it to be avoided as it is used as byte order mark and word joiner (0x2060) is not categorized by unicode as a space. |

Well, 202F NARROW NO-BREAK SPACE (NNBSP) and 180E MONGOLIAN VOWEL SEPARATOR (MVS) are narrower versions of NBSP and could be so displayed. But is the issue here that anything that is not a standard Space be displayed differently than a standard Space. |

I dunno jghali but testing gives me the feeling that scribus considers all non standard spaces as non breaking spaces. Please find the joined 'space lab.sla' file and play with it changing the frame width and seeing how line break adjust with different spaces. One can see that scribus adds a hyphen when breaking on all spaces except normal space. That leads me to believe these are treated as non breaking spaces. Adjusting the word lenghts in the SLA might improve understanding of what is happening too. I agree with richardpaulhall about displaying not standard spaces differently than standard spaces. And in cases there are both breaking and no-break non standard spaces - there could be 2 signs : red underline for no-break non standard spaces as CTRL+Space, and blue underline for breaking non standard spaces. These conventions could be ported to the "display invisible characters" mode of the normal view aswell. (see http://bugs.scribus.net/view.php?id=10280) |

Goal is to know that there in text some other than standard spaces (not only no-breaking space) are used. It is important when we load text from outside sources (formatted text files) - how to recognize that someone use such special chars or not? My propose is using few colors for different kinds of spaces while displaying special characters in window. Dont know what future of SE is. If it will be kept in Scribus than some indication of special spaces will be helpful. Maybe it could be some kind of <XX> code, like <FS> for figure space, <NS> for en width space and so on. |

not sure if many colors will be really helpful here. isn't a bit hard to recognize which color means what type of space? it would be wonderful if we could have different forms which remind to the function of the space... but i'm not sure if it will be easy to find (and draw on canvas) those signs... or would be a tooltip a possibility? on the other side, the future of the SE is imo to become a powerful tool for managing the formatting in a "tagged" way. one could show and hide tags... but, imo, there are too many projects open that i think that we should close some of them before opening the rewriting of the SE... ... but i'd like to see some work on it late next spring... (and why not writing it as a python script and making it customizable?) |

according to http://fr.wikipedia.org/wiki/Espace_ins%C3%A9cable, Unicode got a special character for educationnal purposes whose aim is to display where non breaking spaces are used : U+237D in Unicode/U2300 table. Its called « Caisse ouverte à épaulement » or "SHOULDERED OPEN BOX". See it here : http://upload.wikimedia.org/wikipedia/commons/5/5b/U%2B237D.gif So as to align with Unicode educational purposes, « ? » U+237D seems to be a good candidate. I could not find more explanation on this. |

jghali : http://en.wikipedia.org/wiki/Non-breaking_space states that "No-break thin space, known in Unicode as “Narrow No-Break Space” (U+202F ? narrow no-break space (HTML: ?)). It was introduced in Unicode 3.0 for Mongolian, to separate a suffix from the word stem without indicating a word boundary. Also required for French punctuation (before ?, ! or ;)." So i'm quite glad thin space is no-break in scribus. What else could easily we use before ;, ? and ! ?, in french ?? Unless you add that mongolian space in the menu, for all french writers... |

Agreeing with ale on : it seems difficult to have as many colors and glyphs as there are types of spaces. More over, other non displayed special characters as soft-hyphen are not spaces, but should also be shown in some way in the story editor. Here are various options that would fit well together : - use 2 different signs for breaking / non breaking signs, since being aware of this difference is part of the job editing with the story editor -* use a green U+237D "SHOULDERED OPEN BOX" for all non breaking blank signs -* use green ~ or _ for example for all breaking spaces - use a tooltip (a hint bubble appearing on hovering the sign) so as to display full characteristics of the glyph : name and unicode value. - use a specific color (red) when the glyph is NOT defined in its font |

The reporter has only requested: "should be displayed as red underscore" that is not too complicated I guess. As a user I would like that too. @cezaryece: For users who want to "analyze" a text in detail, maybe a Scribus text frame is not the best place. In our workflow we mainly bring "ready texts" into Scribus. Stil there is a useful font here that helps people who need to know (see) each detail: http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=UnicodeBMPFallbackFont |

interesting font. Maybe it could be used, in other places, when a missing font glyph is used in the SLA ? |
|
|
@MZaske very cool idea Unicode BMP Fallback Font Intended for debugging, this font contains a glyph for every character in the Basic Multilingual plane (including Private Use Area) of Unicode, each glyph consisting of a box enclosing the four hex digits identifying the Unicode scalar value. |
