Voor het gebruik van <a href="/wiki/Reguliere_expressie" title="Reguliere expressie">reguliere expressies</a> met bijvoorbeeld de Unicode-karakterset, zal het programma of de software waarin deze gebruikt worden, wel Unicode moeten ondersteunen. In dat geval zal de <i>regexp</i> <small><code>\s</code></small> ook matchen met alle tekens die tot de whitespaces worden gerekend, maar zal (mogelijk) geen eenletterige <small><code>\</code></small>-<i>sequence</i> bestaan die individueel matchen met de whitespace-karakters die niet in de klassieke ASCII-tabel voorkomen. In plaats daarvan kan op Unicode-karakter worden gematched met de expressie <small><code>\uFFFF</code></small> of <small><code>\u{FFFF}</code></small>, waarin <small><code>FFFF</code></small> dan correspondeert met de hexadecimale waarde van het betreffende karakter.<sup id="cite_ref-regexpinfo_10-1" class="reference"><a href="#cite_note-regexpinfo-10"><span class="cite-bracket">[</span>ref 3<span class="cite-bracket">]</span></a></sup> </p> <div class="toccolours appendix" role="presentation" style="font-size:90%; margin:1em 0 -0.5em; clear:both;"> <div><span style="font-weight:bold">Bronnen, noten en/of referenties</span></div> <p><b>Referenties</b> </p> <div class="reflist" style="list-style-type: decimal;"><div class="mw-references-wrap"><ol class="references"> <li id="cite_note-ascii-pdf-1"><span class="mw-cite-backlink"><a href="#cite_ref-ascii-pdf_1-0">↑</a></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r67679320">.mw-parser-output .taalaanduiding{font-family:sans-serif;font-size:85%;cursor:help;color:var(--color-subtle,#555)}.mw-parser-output .taalaanduiding span{border-bottom:1px dotted var(--color-subtle,#555)}</style><span class="taalaanduiding" title="Taal: Engels">(<span>en</span>) </span><a rel="nofollow" class="external text" href="http://www.cisco.com/c/en/us/td/docs/ios/12_2/configfun/command/reference/ffun_r/frf019.pdf">ASCII Character Set and Hex Values</a> <span typeof="mw:File"><span title="Pdf-document"><img alt="Pdf-document" src="//upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Icons-mini-file_pdf.svg/16px-Icons-mini-file_pdf.svg.png" decoding="async" width="16" height="16" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Icons-mini-file_pdf.svg/24px-Icons-mini-file_pdf.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Icons-mini-file_pdf.svg/32px-Icons-mini-file_pdf.svg.png 2x" data-file-width="16" data-file-height="16" /></span></span> www.cisco.com, geraadpleegd 3 september 2016.</span> </li> <li id="cite_note-regexp-9"><span class="mw-cite-backlink"><a href="#cite_ref-regexp_9-0">↑</a></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r67679320"><span class="taalaanduiding" title="Taal: Engels">(<span>en</span>) </span><a rel="nofollow" class="external text" href="http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_04_02.html">Bash Guide for Beginners - 4.2.2.

Een voorbeeld naar analogie: in een karakterset kunnen alle tekens (en codes) worden benoemd die een "klinker" zijn, maar het is evident dat andersom geen unieke karakter(code) voor "de klinker" bestaat (om deze te tonen).</span> </li> </ol></div></div> </div>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Overgenomen van "<a dir="ltr" href="https://nl.wikipedia.org/w/index.php?title=Whitespace_(karakter)&oldid=58879207">https://nl.wikipedia.org/w/index.php?title=Whitespace_(karakter)&oldid=58879207</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Categorie:Alles" title="Categorie:Alles">Categorieën</a>: <ul><li><a href="/wiki/Categorie:Informatica" title="Categorie:Informatica">Informatica</a></li><li><a href="/wiki/Categorie:Digitale_typografie" title="Categorie:Digitale typografie">Digitale typografie</a></li><li><a href="/wiki/Categorie:Computerstandaard" title="Categorie:Computerstandaard">Computerstandaard</a></li><li><a href="/wiki/Categorie:ISO" title="Categorie:ISO">ISO</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> Deze pagina is voor het laatst bewerkt op 6 mei 2021 om 10:04.</li> <li id="footer-info-copyright">De tekst is beschikbaar onder de licentie <a rel="nofollow" class="external text" href="//creativecommons.org/licenses/by-sa/4.0/deed.nl">Creative Commons Naamsvermelding/Gelijk delen</a>, er kunnen aanvullende voorwaarden van toepassing zijn.
