Invision Community 5: A video walkthrough creating a custom theme and homepage By Matt Thursday at 04:02 PM
Tikhonov Ivan Posted March 31 Posted March 31 (edited) After upgrade we've noticed the new btoa() function and error "failed to execute btoa()" in global_global_core.js As a result, pagination for cyrillic urls stopped working. See https://developer.mozilla.org/en-US/docs/Glossary/Base64#the_unicode_problem As a temporary solution we implemented the convertion between UTF-8 and single-byte representations before call btoa(), like Quote const toBinaryStr = url => { const encoder = new TextEncoder(); const charCodes = encoder.encode(url); const binString = Array.from(charCodes, (byte) => String.fromCodePoint(byte), ).join(""); return binString; }; <...> this._stateKey = `table${btoa(toBinaryStr(this.scope.attr('data-baseurl') ? ips.utils.url.pageParamToPath(this._cleanUpURL(this.scope.attr('data-baseurl')), this._pageParam, 1) : ''))}`; Edited March 31 by Tikhonov Ivan
Tikhonov Ivan Posted April 1 Author Posted April 1 Would you, please, fix this core bug of global_global_core.js soon? It is inconvenient to apply above custom patch every time after clearing system caches. I believe every forums with non-Latin topic urls are affected.
Jim M Posted April 1 Posted April 1 Please ensure that you have applied the latest release and all patches. I have tagged a developer to review what you have posted though. Tikhonov Ivan 1

I have tagged a developer to review what you have posted though. Thanks, Jim. That's the point of latest release as well, compared with v4.7.15 the btoa() function appeared in core java-script and utf-8 character string is unacceptable as a btoa() argument.
Ohanzee Posted April 1 Posted April 1 I am having the same problem on my site with forums that have letters such as 'š', 'đ', 'ž', etc. Tikhonov Ivan 1
Marc Posted April 2 Posted April 2 Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

Stuart Silvester Posted April 3 Posted April 3 We're going to address this in a patch (likely tomorrow) with some other items but in the meantime you can go to AdminCP > Search Engine Optimisation > enable Rewrite FURLs (and follow the instructions). This will work around the issue since it's only a problem when FURLS are not used. Marc 1
Solution Stuart Silvester Posted April 5 Solution Posted April 5 We have released a patch to address this issue. Please go to AdminCP > System > Support and apply the patch from the first/top left box. If you do not see an option to install the patch, you already have the latest release. Additionally, as previously noted, enabling URL Rewriting will also fix this issue. stoo2000, SeNioR-, Marc and 1 other 4
