If it's a usable font, it's actually two different fonts, one in a sort of negative to the other.
You could get a similar effect by getting the word you want to use, outlining it and repeating it: 'SaibreXSaibreXSaibreXSaibreXSaibreXSaibreXSaibreX...'
Copy that text, then use the pathfinder dialogue in Adobe Illustrator to punch that text shape out of a block of colour to create the negative image and paste it underneath your original text. Using this method, you could create an original image that could then be tiled into a texture/pattern.
