Subhash Comic Viewer v2018.04.22 for Android fixes file selector dialog bug
The # symbol is valid for file and directory names. However, in a URL, it is considered a marker for an intra-page bookmark. If such symbols are URL encoded in the published HTML page, then many browsers fail to display the page correctly. Retaining the exact names from the comic archive in the page is therefore not viable. This version of Subhash Comic Viewer safe-renames all files and directories of the extracted comic archive.
Another bug that was fixed was in the file selector. In my Karbonn phone, it crashes in the lala land between the internal storage and the memory card. The fix has been applied to the file manager in Subhash Browser too.
